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_call_new_account --fork Amsterdam

Verify block.gas_used includes state gas from CALL creating accounts.

A contract does CALL(value=1) to a non-existent address (charges GAS_NEW_ACCOUNT state gas) then SSTORE. Combined with a STOP tx, the 2D max must reflect state gas from account creation.
