With LH v8.1.3 supporting Fulu-on-Gnosis, we no longer need these DB migrations. All Lighthouse nodes running in prod will soon be updated to LH v8.0.0+ and schema v28+.
This PR helps with Gloas fork choice changes, by allowing us to avoid updating old schema migrations when adding V29 for Gloas:

Serves envelope by range and by root requests. Added PayloadEnvelopeStreamer so that we dont need to alter upstream code when we introduce blinded payload envelopes.

Closes:
- https://github.com/sigp/lighthouse/issues/8958
- Update the `HotColdStore` to handle storage of cold states.
- Update `BeaconSnapshot` to hold the execution envelope. This is required to make `chain_dump`-related checks sane, and will be generally useful (see: https://github.com/sigp/lighthouse/issues/8956).
- Bug fix in the `BlockReplayer` for the case where the starting state is already `Full` (we should not try to apply another payload). This happens on the cold DB path because we try to replay from the closest cached state (which is often full).
- Update `test_gloas_hot_state_hierarchy` to cover the cold DB migration.

Update spec code for compliance with spec v1.7.0-alpha.3: https://github.com/ethereum/consensus-specs/releases/tag/v1.7.0-alpha.3
The actual consensus changes are minimal. There are few more changes that are only relevant to fork choice or P2P validation that we will pick up in future PRs.
The change "Ignore beacon block if parent payload unknown" is currently covered in a hacky way by `load_parent` and can be improved once we have fork choice.
The change "Add parent_block_root to bid filtering key" is relevant to bid gossip validation, which we don't have at all in unstable yet.

Closes:
- https://github.com/sigp/lighthouse/issues/8869
- Update `BlockReplayer` to support replay of execution payload envelopes.
- Update `HotColdDB` to load payload envelopes and feed them to the `BlockReplayer` for both hot + cold states. However the cold DB code is not fully working yet (see: https://github.com/sigp/lighthouse/issues/8958).
- Add `StatePayloadStatus` to allow callers to specify whether they want a state with a payload applied, or not.
- Fix the state cache to key by `StatePayloadStatus`.
- Lots of fixes to block production and block processing regarding state management.
- Initial test harness support for producing+processing Gloas blocks+envelopes
- A few new tests to cover Gloas DB operations

#7330
Removes `c-kzg` from our `kzg` crate and rely fully on the `rust_eth_kzg` crate.
This removes the old `Blob` type entirely and instead handles `rust_eth_kzg::KzgBlobRef`s directly which allows us to avoid some extra stack allocations . Similarly, we make `Bytes32` and `Bytes48` type aliases rather than structs as this fits better with the new `rust_eth_kzg` API.

Mark pointed out that these APIs will require updates for Gloas, so I figured we may as well get rid of them. As far as I know, blockprint was the only use case and it is now defunct. The consensus block value is included in getBlock API responses, so there's no reason for VCs to use the `POST` API, and there is now a standard API for the rewards of canonical blocks. The SSE event was non-standard, and likely only used by blockprint as well.

Following the release of Rust v1.94.0 there are new Clippy lints which do not pass and are blocking CI (which pulls in the latest version of Rust)
This is pretty much the minimum just to get CI running again. Most of the errors involve error types being too large. For now I've added allows but later it might be worth doing a refactor to `Box` or otherwise remove the problematic error types.

We received a bug report of a node restarting custody backfill unnecessarily after upgrading to Lighthouse v8.1.1. What happened is:
- User started LH v8.0.1 many months ago, CGC updated 0 -> N but the CGC was not eagerly persisted.
- LH experienced an unclean shutdown (not sure of what type).
- Upon restarting (still running v8.0.1), the custody context read from disk contains CGC=0: `DEBUG Loaded persisted custody context custody_context: CustodyContext { validator_custody_count: 0, ...`).
- CGC updates again to N, retriggering custody backfill: `DEBUG Validator count at head updated old_count: 0, new_count: N`.
- Custody backfill does a bunch of downloading for no gain: `DEBUG Imported historical data columns epoch: Epoch(428433), total_imported: 0`
- While custody backfill is running user updated to v8.1.1, and we see logs for the CGC=N being peristed upon clean shutdown, and then correctly read on startup with v8.1.1.
- Custody backfill keeps running and downloading due to the CGC change still being considered in progress.
- Call `persist_custody_context` inside the `register_validators` handler so that it is written to disk eagerly whenever it changes. The performance impact of this should be minimal as the amount of data is very small and this call can only happen at most ~128 times (once for each change) in the entire life of a beacon node.
- Call `persist_custody_context` inside `BeaconChainBuilder::build` so that changes caused by CLI flags are persisted (otherwise starting a node with `--semi-supernode` and no validators, then shutting it down uncleanly would cause use to forget the CGC).
These changes greatly reduce the timespan during which an unclean shutdown can create inconsistency. In the worst case, we only lose backfill progress that runs concurrently with the `register_validators` handler (should be extremely minimal, nigh impossible).
