During custody backfill sync if a peer fails to serve columns for a batch don't penalize them more than once per batch

Using `state.fork` is a bit sketchy at the fork boundary. It's safer to just use the payload attestations slot

Forgot to add `ENGINE_GET_BLOBS_V3` to `LIGHTHOUSE_CAPABILITIES`.

#8314 left a few ugly potentially panicking location behind - all of them believed to be unreachable, but this PR fixes them regardless for good hygiene.
Update to `ethereum_ssz 0.10.4` for two new helpers: `not_inplace` and `clone_zeroed`.
Remove remaining `expect` and `todo!` in favour of these helpers and one new fallible (but practically infallible) method.

- PR https://github.com/sigp/lighthouse/pull/9305 wants to store PTCs in the committee cache.
BUT the http API route wants to use the committee cache and insert historical committees (i.e. given state at epoch 1000, compute and store the committee for epoch 900).
If we want a single cache to serve both use cases we need to:
- Have entries in the committee cache that have no PTC: Makes reading PTCs from the cache not deterministic
- Compute historical PTC: A bunch of complicated code that's useless
Instead we can add a separate cache for the API, very simple one, that caches committees only. And have the one in the beacon chain compute and cache PTCs always.
### Performance impact
Slightly additional memory cost for users of the `beacon/states/committees` route. Caching is almost equivalent, except for queries of recent committees that may already exist in the beacon chain's committee cache.
### AI disclousure
This PR was written by hand 90%. Claude fixed some warp type issues

While working on this code in another branch I noticed we had this messy, complicated and incorrect code about SPRP (slots-per-restore-point), which is no longer a relevant concept since the introduction of hot state diffs.
In the name of simplicity, I've removed any kind of hinting here in favour of a simple out of bounds error. The benefit of adding complex hinting code (which is not tested) to such a function is not worth it IMO. Users will work it out (or ask) if we just tell them their request is out of bounds.

In Gloas, beacon blocks are imported into fork choice immediately - the payload envelope and data columns arrive
separately. KZG commitments moved from the column sidecar into the execution payload bid, so the existing
`DataAvailabilityChecker` (which assumes block and data are coupled) can't be used for Gloas.
* Introduced `PendingPayloadCache` to keep track of payload and data columns per block root.
* Added gossip column verification
* Added support for Gloas data column reconstruction
* Payload envelope verification simplified: removed `MaybeAvailableEnvelope`, `ExecutedEnvelope`, `EnvelopeImportData`
Not yet implemented (tracked with TODOs):
- Proper lookup sync for Gloas columns arriving before blocks
- Partial column merging for Gloas
- Moving `load_gloas_payload_bid` disk reads off the async runtime
- Backfill/range sync for Gloas
Based on @eserilev's PR and work in progress. See also #9202 for verification.

Using the `ignore-ws-check` doesn't actually let you start up a node thats outside the weak subjectivity period

Test helpers `add_attested_block_at_slot` and `add_attested_blocks_at_slot` accepted `state_root` argument which was computed before applying the block.

We got in a little bit of trouble in devnet-3. After gossip verifying an envelope and before importing it, we got the following error
```
May 07 08:04:24.383 WARN Execution payload envelope rejected reason: "EnvelopeProcessingError(WithdrawalsRootMismatch { state: 0x852d38aaecc9f4e2e309919f74020c7bbcf050fea4a20edf3304f171e44ee9d5, payload:
```
The envelope had already passed gossip verification checks and was correctly propagated to the network, we should not penalize peers for doing this. This caused our node to isolate itself from the rest of the network. This PR removes peer penalties for any envelope that passes gossip validation

Part of #8828 for the stateful path and helps align gloas `produceBlockV4` with beacon-APIs [PR](https://github.com/ethereum/beacon-APIs/pull/580)
- Plumb `include_payload` query through the handler. Ignored for now since stateless mode isn't wired up yet
- Add `execution_payload_included` metadata field + `Eth-Execution-Payload-Included` header per spec. Both `false` until stateless lands
- Drop the `{builder_index}` segment from the envelope GET URL since no longer included in spec

We have a legacy `TestRandom` trait which generates random types for testing and fuzzing.
This function overlaps with `arbitrary` which is used very commonly in the ecosystem.
Remove `TestRandom` and generate random type instances using `Arbitrary`.
