Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_state_gas_calldata_floor.py::test_calldata_floor_counts_toward_block_gas --fork Amsterdam

Verify the calldata floor is charged to the block's execution gas.

With a STOP callee and large zero-byte calldata the floor exceeds the actual execution gas charge, so the transaction contributes the floor (not the pre-floor charge) to the header gas_used.
