Gives a 100x speed boost for this operation which happens during
optimistic sync when computing the block hash.

The comment in `readExecutionTransaction` is not actually relevant when
the `rlp.decode` template is called from a non-generic function.
The function still cannot be simply inlined; `is_valid_versioned_hashes`
is itself generic and would require an `export eth_types_rlp` to work
properly (generic sandwich issue). The non-generic function wrapper
seems simpler and avoids injecting RLP into importing modules.
Normally, running LC and DAG sync at same time is fine, but on tiny
devnet where some peer may not support the LC data, we can end up in
situation where peer gets disconnected when DAG is in sync, because
DAG sync never uses any req/resp on local devnet (perfect nw conditions)
so the LC sync over minutes removes the peer as sync is stuck.
We don't need to actively sync LC from network if DAG is already synced,
preventing this specific low peer devnet issue (there are others still).
LC is still locally updated when DAG finalized checkpoint advances.
* check blob versioned hashes when no EL is connected
When no EL is conencted, we have to at the very least ensure that the
data in the beacon block is consistent with the execution payload.
We already do this for the block hash, but also have to do it for the
`blob_kzg_commitments`. To validate that they are linked with the
execution payload, we have to RLP decode all EIP-4844 blob transactions
and compare their blob versioned hashes with the hashed commitments.
* simplify loop in case where `blob_versioned_hashes` doesn't exist
* skip blob transaction parsing pre Deneb
* remove option to select Capella fork choice algo
With Deneb having run stable for quite a while now, it's time to remove
the option to select the prior fork choice algo from Capella.
* also remove usage from test
Followup on incorrect upgrade procedure in #6375 where `blob_gas_used`
was accidentally copied into `excess_blob_gas` when running Electra
`LightClientStore` with earlier `LightClient(Bootstrap|Update)`.
The fork digest determines the underlying data type on libp2p gossip,
so it's important to use the matching fork digest instead of picking
whatever wall epoch happens to be.
To avoid "forked" types creeping into `BlobSidecar`, move the reduction
to `BlobSidecarInfoObject` to the sole caller. The info object is fork
agnostic, so does not need "forked" if `BlobSidecar` ever updates.
* Fix blob syncing for Electra
`BlobSidecar` requests on libp2p have a context prefix based on:
> The `<context-bytes>` field is calculated as context =
> `compute_fork_digest(fork_version, genesis_validators_root)`
We currently only process blobs if that indicates Deneb, meaning that
on Electra we incorrectly report `InvalidContextBytes` and refuse to
process the blob response data.
Fix this, and also ensure that the code no longer needs maintenance
with every fork unrelated to blobs.
* fix
When no EL is connected, it is still required to validate the block hash
of `ExecutionPayload` to prevent attacks that trick us into attesting to
a circular chain with invalid in-between block hashes. This is already
done through Deneb but was still missing in Electra to be rectified now.
