I found myself having to update this code for Gloas, and figured we may as well delete it seeing as it doesn't work.

Fix the failure of the beacon-chain tests for phase0/altair, which now only runs nightly.
Just skip the payload invalidation tests, they don't make any sense prior to Bellatrix anyway.

I accidentally broke `unstable` while merging some missed commits from `release-v8.0`. The merge was clean but semantically broken, and I didn't notice because I pushed without running CI 😬
- Fix the regression test added for #8528, for compatibility with the recent `RpcBlock` changes. I'm passing `is_available = false` which seems correct for this test.

#8652
- This removes instances of `BeaconStateError` from `eth_spec.rs`, and replaces them directly with `ArithError` which can be trivially converted back to `BeaconStateError` at the call site.
- Also moves the state related methods on `ChainSpec` to be methods on `BeaconState` instead. I think this might be a more natural place for them to exist anyway.

Closes#8426
Added a new regression test: `reproduction_unaligned_checkpoint_sync_pruned_payload`.
This test reproduces the bug where unaligned checkpoint syncs (skipped slots at epoch boundaries) fail to import the anchor block's execution payload when `prune_payloads` is enabled.
The test simulates the failure mode by:
- Skipping if execution payloads are not applicable.
- Creating a harness with an unaligned checkpoint (gap of 3 slots).
- Configuring the client with prune_payloads = true.
It asserts that the Beacon Chain builds successfully (previously it panicked with `MissingFullBlockExecutionPayloadPruned`), confirming the fix logic in `try_get_full_block`.

There are certain crates which we re-export within `types` which creates a fragmented DevEx, where there are various ways to import the same crates.
```rust
// consensus/types/src/lib.rs
pub use bls::{
AggregatePublicKey, AggregateSignature, Error as BlsError, Keypair, PUBLIC_KEY_BYTES_LEN,
PublicKey, PublicKeyBytes, SIGNATURE_BYTES_LEN, SecretKey, Signature, SignatureBytes,
get_withdrawal_credentials,
};
pub use context_deserialize::{ContextDeserialize, context_deserialize};
pub use fixed_bytes::FixedBytesExtended;
pub use milhouse::{self, List, Vector};
pub use ssz_types::{BitList, BitVector, FixedVector, VariableList, typenum, typenum::Unsigned};
pub use superstruct::superstruct;
```
This PR removes these re-exports and makes it explicit that these types are imported from a non-`consensus/types` crate.

Fix a bug in `verify_header_signature` which tripped up some Lighthouse nodes at the Fusaka fork. The bug was a latent bug in a function that has been present for a long time, but only used by slashers. With Fulu it entered the critical path of blob/column verification -- call stack:
- `FetchBlobsBeaconAdapter::process_engine_blobs`
- `BeaconChain::process_engine_blobs`
- `BeaconChain::check_engine_blobs_availability_and_import`
- `BeaconChain::check_blob_header_signature_and_slashability`
- `verify_header_signature`
Thanks @eserilev for quickly diagnosing the root cause.
Change `verify_header_signature` to use `ChainSpec::fork_at_epoch` to compute the `Fork`, rather than using the head state's fork. At a fork boundary the head state's fork is stale and lacks the data for the new fork. Using `fork_at_epoch` ensures that we use the correct fork data and validate transition block's signature correctly.

Take 2 of #8390.
Fixes the race condition properly instead of propagating the error. I think this is a better alternative, and doesn't seem to look that bad.
* Lift node id loading or generation from `NetworkService ` startup to the `ClientBuilder`, so that it can be used to compute custody columns for the beacon chain without waiting for Network bootstrap.
I've considered and implemented a few alternatives:
1. passing `node_id` to beacon chain builder and compute columns when creating `CustodyContext`. This approach isn't good for separation of concerns and isn't great for testability
2. passing `ordered_custody_groups` to beacon chain. `CustodyContext` only uses this to compute ordered custody columns, so we might as well lift this logic out, so we don't have to do error handling in `CustodyContext` construction. Less tests to update;.

This is an optimisation targeted at Fulu networks in non-finality.
While debugging on Holesky, we found that `state_root_at_slot` was being called from `prepare_beacon_proposer` a lot, for the finalized state:
2c9b670f5d/beacon_node/http_api/src/lib.rs (L3860-L3861)
This was causing `prepare_beacon_proposer` calls to take upwards of 5 seconds, sometimes 10 seconds, because it would trigger _multiple_ beacon state loads in order to iterate back to the finalized slot. Ideally, loading the finalized state should be quick because we keep it cached in the state cache (technically we keep the split state, but they usually coincide). Instead we are computing the finalized state root separately (slow), and then loading the state from the cache (fast).
Although it would be possible to make the API faster by removing the `state_root_at_slot` call, I believe it's simpler to change `state_root_at_slot` itself and remove the footgun. Devs rightly expect operations involving the finalized state to be fast.

`beacon-chain-tests` is now regularly taking 1h+ on CI since Fulu fork was added.
This PR attemtpts to reduce the test time by bringing down the number of blobs generated in tests - instead of generating 0..max_blobs, the generator now generates 0..1 blobs by default, and this can be modified by setting `harness.execution_block_generator.set_min_blob_count(n)`.
Note: The blobs are pre-generated and doesn't require too much CPU to generate however processing a larger number of them on the beacon chain does take a lot of time.
This PR also include a few other small improvements
- Our slowest test (`chain_segment_varying_chunk_size`) runs 3x faster in Fulu just by reusing chain segments
- Avoid re-running fork specific tests on all forks
- Fix a bunch of tests that depends on the harness's existing random blob generation, which is fragile
beacon chain test time on test machine is **~2x** faster:
### `unstable`
```
Summary [ 751.586s] 291 tests run: 291 passed (13 slow), 0 skipped
```
### this branch
```
Summary [ 373.792s] 291 tests run: 291 passed (2 slow), 0 skipped
```
The next set of tests to optimise is the ones that use [`get_chain_segment`](77a9af96de/beacon_node/beacon_chain/tests/block_verification.rs (L45)), as it by default build 320 blocks with supernode - an easy optimisation would be to build these blocks with cgc = 8 for tests that only require fullnodes.

The beacon API spec wasn't updated to use the Fulu definition of `dependent_root` for the proposer duties endpoint. No other client updated their logic, so to retain backwards compatibility the decision has been made to continue using the block root at the end of epoch `N - 1`, and introduce a new v2 endpoint down the track to use the correct dependent root.
Eth R&D discussion: https://discord.com/channels/595666850260713488/598292067260825641/1433036715848765562
Change the behaviour of the v1 endpoint back to using the last slot of `N - 1` rather than the last slot of `N - 2`. This introduces the possibility of dependent root false positives (the root can change without changing the shuffling), but causes the least compatibility issues with other clients.

During custody backfill sync there could be an edge case where we update CGC at the same time where we are importing a batch of columns which may cause us to incorrectly overwrite values when calling `backfill_validator_custody_requirements`. To prevent this race condition, the expected cgc is now passed into this function and is used to check if the expected cgc == the current validator cgc. If the values arent equal, this probably indicates that a very recent CGC occurred so we do not prune/update values in the `epoch_validator_custody_requirements` map.

Replace all instances of `VariableList::from` and `FixedVector::from` to their `try_from` variants.
While I tried to use proper error handling in most cases, there were certain situations where adding an `expect` for situations where `try_from` can trivially never fail avoided adding a lot of extra complexity.

Addresses #8218
A simplified version of #8241 for the initial release.
I've tried to minimise the logic change in this PR, although introducing the `NodeCustodyType` enum still result in quite a bit a of diff, but the actual logic change in `CustodyContext` is quite small.
The main changes are in the `CustdoyContext` struct
* ~~combining `validator_custody_count` and `current_is_supernode` fields into a single `custody_group_count_at_head` field. We persist the cgc of the initial cli values into the `custody_group_count_at_head` field and only allow for increase (same behaviour as before).~~
* I noticed the above approach caused a backward compatibility issue, I've [made a fix](15569bc085) and changed the approach slightly (which was actually what I had originally in mind):
* when initialising, only override the `validator_custody_count` value if either flag `--supernode` or `--semi-supernode` is used; otherwise leave it as the existing default `0`. Most other logic remains unchanged.
All existing validator custody unit tests are still all passing, and I've added additional tests to cover semi-supernode, and restoring `CustodyContext` from disk.
Note: I've added a `WARN` if the user attempts to switch to a `--semi-supernode` or `--supernode` - this currently has no effect, but once @eserilev column backfill is merged, we should be able to support this quite easily.
Things to test
- [x] cgc in metadata / enr
- [x] cgc in metrics
- [x] subscribed subnets
- [x] getBlobs endpoint

#7603
#### Custody backfill sync service
Similar in many ways to the current backfill service. There may be ways to unify the two services. The difficulty there is that the current backfill service tightly couples blocks and their associated blobs/data columns. Any attempts to unify the two services should be left to a separate PR in my opinion.
#### `SyncNeworkContext`
`SyncNetworkContext` manages custody sync data columns by range requests separetly from other sync RPC requests. I think this is a nice separation considering that custody backfill is its own service.
#### Data column import logic
The import logic verifies KZG committments and that the data columns block root matches the block root in the nodes store before importing columns
#### New channel to send messages to `SyncManager`
Now external services can communicate with the `SyncManager`. In this PR this channel is used to trigger a custody sync. Alternatively we may be able to use the existing `mpsc` channel that the `SyncNetworkContext` uses to communicate with the `SyncManager`. I will spend some time reviewing this.
