fix startup after BN exited between head and finalized blocks updates (#5617)
When the BN exits after writing new `head` to database, but before
completing the `updateFinalizedBlocks` call, the database is slightly
inconsistent due to the partial write. We currently fail to start up
after that. Fix that by catching up on partial `updateFinalizedBlocks`
tasks on start up, and add a test for this edge case.

Split sync committee message score in range, so lexicographic scores will not intersect with normal one.
Lexicographic scores should be below to normal scores.

* Address review comments.
Fix aggregated attestation scoring to use MAX_VALIDATORS_PER_COMMITTEE.
Fix sync committee contributions to use SYNC_SUBCOMMITTEE_SIZE.
Add getUniqueVotes test vectors.

update Deneb for blob sidecar inclusion proofs (#5565)

- https://github.com/ethereum/consensus-specs/pull/3531

Associated beacon-API / builder-specs still TBD; minimal changes done
to compile in similar style to previous spec, but not standardized yet.

align `Beacon(Block(Body)?|State)Type` with other fork sugar (#5483)
The templates for `BeaconBlock`, `BeaconBlockBody` and `BeaconState`
are the only ones using a `macro` mechanism for code generation.
This prevents using the dot-syntax style `consensusFork.BeaconFoo`
in some situations, and also tends to trigger naming conflicts,
requiring the `Type` suffix. Furthermore, the `macro` only works
for types that are re-defined in every single `ConsensusFork`.

Replacing with the simpler but more verbose approach used for other
types for consistency and to avoid the downsides of the `macro`.

Furthermore, simplify `test_fixture_sanity_blocks` to use `forks` sugar.

generalize `commonAncestor` function to `BlockId` (#5192)
To enable additional use cases, e.g., `/states/###/randao` beacon API,
`ShufflingRef` acceleration logic needs to be able to operate on parts
of the DAG that do not have `BlockRef`. Changing `commonAncestor` to
act on `BlockId` instead of `BlockRef` is a step toward that and also
simplifies the logic some more.

accelerate RANDAO computation for post-merge blocks (#5190)
Post-merge blocks contain all information to directly obtain RANDAO
without having to load any additional info. Take advantage of that to
further accelerate `ShufflingRef` computation. Note that it is still
necessary to verify that `blck` / `state` share a sufficiently recent
ancestor for the purpose of computing attester shufflings.

segregate sync committee messages by period / fork (#4953)
`SyncCommitteeMsgPool` grouped messages by their `beacon_block_root`.
This is problematic around sync committee period boundaries and forks.
Around sync committee period boundaries, members from both the current
and next sync committee may sign the same `beacon_block_root`; mixing
the signatures from both committees together is a mistake. Likewise,
around fork transitions, the `signing_root` changes, so those messages
also need to be segregated.

accelerate `getShufflingRef` (#4911)
When an uncached `ShufflingRef` is requested, we currently replay state
which can take several seconds. Acceleration is possible by:

1. Start from any state with locked-in `get_active_validator_indices`.
   Any blocks / slots applied to such a state can only affect that
   result for future epochs, so are viable for querying target epoch.
   `compute_activation_exit_epoch(state.slot.epoch) > target.epoch`

2. Determine highest common ancestor among `state` and `target.blck`.
   At the ancestor slot, same rules re `get_active_validator_indices`.
   `compute_activation_exit_epoch(ancestorSlot.epoch) > target.epoch`

3. We now have a `state` that shares history with `target.blck` up
   through a common ancestor slot. Any blocks / slots that the `state`
   contains, which are not part of the `target.blck` history, affect
   `get_active_validator_indices` at epochs _after_ `target.epoch`.

4. Select `state.randao_mixes[N]` that is closest to common ancestor.
   Either direction is fine (above / below ancestor).

5. From that RANDAO mix, mix in / out all RANDAO reveals from blocks
   in-between. This is just an XOR operation, so fully reversible.
   `mix = mix xor SHA256(blck.message.body.randao_reveal)`

6. Compute the attester dependent slot from `target.epoch`.
   `if epoch >= 2: (target.epoch - 1).start_slot - 1 else: GENESIS_SLOT`

7. Trace back from `target.blck` to the attester dependent slot.
   We now have the destination for which we want to obtain RANDAO.

8. Mix in all RANDAO reveals from blocks up through the `dependentBlck`.
   Same method, no special handling necessary for epoch transitions.

9. Combine `get_active_validator_indices` from `state` at `target.epoch`
   with the recovered RANDAO value at `dependentBlck` to obtain the
   requested shuffling, and construct the `ShufflingRef` without replay.

late-added validators)
* track when we performed a doppel-detectable activity (attesting) so as
to avoid false positives

adding a validator dynamically just after startup)
