simulators/ethereum/engine: Fixes from interop meeting

[marioevz]

Changes Included

• Invalid payload fields that can be detected by static check before sync are now optional, therefore INVALID and SYNCING can be accepted for payloads that can be detected to be invalid even before sync
• Invalid payloads with an invalid transaction now use more plausible values. E.g. nonce < 2**64-1, gasLimit > 0
• ForkchoiceUpdatedV2 then ForkchoiceUpdatedV3 Valid Payload Building Requests now does not send blob transactions before Cancun fork.
