Allow NewPayloadV2 for pre-Shanghai blocks (#6604)

Browse Source 
This is a fix for
[withdrawal-devnet-3](https://forkmon.withdrawal-devnet-3.ethpandaops.io/).
The problem was that CL calls `NewPayloadV2` for pre-Shanghai blocks
with `nil` withdrawals, which is OK, but that `nil` was erroneously
converted into an empty array, causing block hash mismatch.
