* avoid potentially subtle template/function symbol name interactions
* use warn instead of error in getExecutionPayload codepath to ensure lack of ambiguity
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.
The 40s allotted for setting up a local testnet can sometime be exceeded
when CI is busy. Bumping it by 20s should reduce that risk.
Example, where the entire slots 0 and 1 were missed:
```
{"lvl":"INF","ts":"2023-11-22 18:33:32.000+00:00","msg":"Scheduling first slot action","topics":"beacnde","startTime":"8s999ms800us826ns","nextSlot":2,"timeToNextSlot":"3s199us174ns"}
```
Simplify best `LightClientUpdate` collection by tracking only canonical
data instead of tracking the best update across all branches within the
sync committee period.

* reorder gossip validation checks
Doing the coverage check only after the corresponding committee index is
known allows optimization by early rejecting invalid data.
* use same helper for individual attestations as well
This PR brings down the time to send 100 attestations from ~1s to
~100ms, making it feasible to run 10k validators on a single node (which
regularly send 300 attestations / slot).
This is done by batching the slashing protection database write in a
single transaction thus avoiding a slow fsync for every signature -
effects will be more pronounced on slow drives.
The benefit applies both to beacon and client validators.
When creating new LC updates, information about the parent block's post
state must be available (cached), but information about current block's
post state is not yet required. Caching information about the current
block's post state can be delayed, simplifying the LC data collection
logic a bit and allowing more future flexibility with the cache design.
The proposed change ensures that VC validators are registered with the builder specified by the `--payload-builder-url` argument even if the beacon node has no attached validators. It also prevent such validators from being unintentionally registered with builders configured for specific attached validators by the keymanager api.
Per the current specs, the VC have no way to specify which builders the BN should use on a per-node basis, so for the time being we have to resort to using the BN fallback default builder URL for VC validators.
When new finality is reached without supermajority sync committee
support, trigger another event push on beacon-API and libp2p once
the finality gains supermajority support.
