fix(anvil): track Amsterdam block gas accounting

[Perico-perica46]

Motivation

AnvilBlockExecutor still accumulated tx_gas_used() as both the receipt cumulative gas and the block gas total. After Amsterdam/EIP-8037, revm splits regular gas and state gas, and the block header should use the maximum of the block regular gas and block state gas while receipts keep cumulative transaction gas.

Anvil's node setup also set the hardfork directly on a default CfgEnv, which left spec-dependent gas params and the Amsterdam EIP-8037 flag stale for explicit and auto-detected hardforks.

Solution

Initialize and update Anvil's CfgEnv through revm's spec-aware gas parameter APIs. Track receipt cumulative gas separately from regular/state block gas in AnvilBlockExecutor. Use the Amsterdam-aware gas accumulator for block availability and final BlockExecutionResult::gas_used, and return GasOutput::with_state_gas so downstream executor consumers preserve both gas components.

Add an Amsterdam integration test that mines a contract creation transaction and checks the block header gas uses split block gas accounting instead of receipt cumulative gas.
