Optimize finalized chain sync by skipping newPayload messages (#3738)

## Issue Addressed

#3704 

## Proposed Changes
Adds is_syncing_finalized: bool parameter for block verification functions. Sets the payload_verification_status to Optimistic if is_syncing_finalized is true. Uses SyncState in NetworkGlobals in BeaconProcessor to retrieve the syncing status.

## Additional Info
I could implement FinalizedSignatureVerifiedBlock if you think it would be nicer.
