core: fix EIP-7778 block gas accounting to exclude refunds

Browse source 
The miner accumulates result.UsedGas (post-refund) into the block
header's GasUsed via ApplyTransactionWithEVM, but the validator
accumulates receipt.GasUsed (which is result.MaxUsedGas = pre-refund
for Amsterdam) into its local gas total. This causes every proposed
block containing refund-generating transactions to be rejected with
"invalid gas used" after the Gloas fork.

Use result.MaxUsedGas (pre-refund gas) for block gas accumulation
when Amsterdam is active, matching EIP-7778's requirement that block
gas accounting excludes refunds.
