PR Description
Based on top of #4456
Kind of quick fix to support the Optimistic syncing:
block.slot < currentSlot - 128) as 'finalized' which need noexecutionPayloadandcheckOnTerminalPowBlockConditionsvalidationThe general idea of production implementation is to queue those validations while syncing, drop validations for blocks which become finalized, execute the remaining validations when the sync completes. Probably makes sense to update the head upon EL validations pass
