This PR adds the "FULU" beacon chain config entries for all networks and
fixes the select statements that choose the appropriate engine API call
versions (no new version there but the "default" was always the first
version; now it's the latest version so no need to change unless there
is actually a new version).
New beacon checkpoints are also added for mainnet, sepolia and hoodi
(not for holesky because it's not finalizing at the moment).
Note that though unrelated to fusaka, the log indexer checkpoints are
also updated for mainnet (not for the other testnets, mainly because I
only have mainnet synced here on my travel SSD; this should be fine
though because the index is also reverse generated for a year by default
so it does not really affect the indexing time)

This updates the blsync base types for the Electra fork. I've been
testing, and it doesn't seem to make blsync fully work on Electra. But
I'd still like to get this in to make some progress.

This PR moves chain config related code (config file processing, fork
logic, network defaults) from `beacon/types` and `beacon/blsync` into
`beacon/params` while the command line flag logic of the chain config is
moved into `cmd/utils`, thereby removing the cli dependencies from
package `beacon` and its sub-packages.
This change brings geth into compliance with the current engine API
specification for the Prague fork. I have moved the assignment of
ExecutionPayloadEnvelope.Requests into BlockToExecutableData to ensure
there is a single place where the type is removed.
While doing so, I noticed that handling of requests in the miner was not
quite correct for the empty payload. It would return `nil` requests for
the empty payload even for blocks after the Prague fork. To fix this, I
have added the emptyRequests field in miner.Payload.
This PR adds an extra mechanism to sync.HeadSync that tries to retrieve the latest finality update from every server each time it sends an optimistic update in a new epoch (unless we already have a validated finality update attested in the same epoch).
Note that this is not necessary and does not happen if the new finality update is delivered before the optimistic update. The spec only mandates light_client_finality_update events when a new epoch is finalized. If the chain does not finalize for a while then we might need an explicit request that returns a finality proof that proves the same finality epoch from the latest attested epoch.
This adds support for the Deneb beacon chain fork, and fork handling
in general, to the beacon chain light client implementation.
