Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_block_2d_gas_accounting.py::test_block_gas_used_create_tx --fork Amsterdam

Verify block.gas_used includes intrinsic state gas from CREATE txs.

Contract creation charges GAS_NEW_ACCOUNT as intrinsic state gas. Combined with a STOP tx, verify the 2D max is correct.
