refactor(tests): add checklist marker for eip7883

[LouisTsai-Csie]

🗒️ Description

EIP-7883 updates the gas calculation formula. This PR marks the appropriate checklist item for the eip.

This category aligns with the Gas Cost Changes section, but since test coverage in the previous fork was incomplete, I’ve included it under New Precompiles for review.

New Precompiles - Link

• Call contexts
  • CALL
  • DELEGATECALL
  • STATICCALL
  • CALLCODE
  • Transaction Entry-point
  • Initcode call
  • Precompile as Set-code Delegated Address -> used in test_set_code_txs.py.
• Inputs
• Value Transfer
  • Minimum Fee Precompile: No value transfer is required
  • [x]No-Fee Precompile
• Out-of-bounds checks
  • precompile/test/out_of_bounds/max
  • precompile/test/out_of_bounds/max_plus_one
• Input Lengths
  • Zero-length Input
  • Static Required Input Length
  • Dynamic Required Input Length
• Gas usage
  • Constant Gas Cost: The gas cost is dynamic
  • Variable Gas Cost
  • Excessive Gas
• Fork transition
  • Pre-fork Block Call
  • Cold/Warm Precompile Address State: Note Modexp is not a new one, so it is warm even before fork activation

I am not very sure about intention for gas_cost_changes/test/out_of_gas.

For the Inputs section in eip7883, i would like to update it later after a separate PR for eip7823 refactoring.

LGTM! Really glad we are checking the precompile result too, and nice gas used parameterization!

Could we also overwrite the test id for the transition test:

@pytest.mark.parametrize(
    "modexp_input,modexp_expected,gas_old,gas_new",
    [
        pytest.param(Spec.modexp_input, Spec.modexp_expected, 200, 1200),
    ],
    ids=[""],
)

Otherwise we get a huge test id :)

Ohh, and ethereumjs mentioned it was a pain to parse test_modexp_invalid_inputs so we should do the same there:

@pytest.mark.parametrize(
    "modexp_expected,call_succeeds",
    [
        pytest.param(bytes(), False),
    ],
    ids=[""],
)
