fix: use parent state with payload for block production and block reward

[twoeths]

Motivation

when reviewing #9731 I found 2 places we missed using parent state with payload applied:

• in block production, when produceCommonBlocBody(), this is mainly to query attestations and get correct reward. We also need it to get correct voluntary exits
• in block reward

in block production, we have different places to call withParentPayloadApplied(), it's best to prepare this state once and pass to downstream apis

Description

• enhance BlockAttributes to include parentState, parentStateWithPayload and parentExecutionRequests
  • parentState is mostly used to compute block state's root
  • parentStateWithPayload is just the same to parentState if pre-gloas or building on EMPTY
  • parentExecutionRequests is included so that we don't have to get it twice (it could be fetched from db)
• prepare parentState, parentStateWithPayload and parentExecutionRequests for produceBlockV4() and pass to downstream apis
• we don't have to filter voluntary exits again since we already used parentStateWithPayload for produceCommonBlockBody()
• fix block reward api by applying parent payload requests
