Documentation for tests/amsterdam/eip8038_state_access_gas_cost_increase/test_eip_mainnet.py::test_extcodesize@2867859a.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip8038_state_access_gas_cost_increase/test_eip_mainnet.py::test_extcodesize --fork Amsterdam

EXTCODESIZE pays the EIP-8038 account access plus the code-read surcharge and succeeds, returning the target's non-zero code size.
