Additional test coverage for EIP-7976: Increase calldata floor cost.

This module tests: 1. Token calculation verification with different byte compositions 2. Maximum calldata size handling 3. Memory expansion interaction with floor cost 4. Nested contract calls verification 5. Exact threshold boundary testing 6. Authorization list gas cost verification 7. Gas refund cap interaction with floor cost

Test Functions Overview

Name	Type	Cases (Amsterdam)	Description
test_authorization_list_intrinsic_gas	state_test	3	Verify authorization list gas costs are included in intrinsic gas.
test_exact_threshold_boundary	state_test	12	Find exact calldata byte count N where floor_cost == intrinsic_cost.
test_maximum_calldata_size	state_test	1	Test transaction with large calldata size (~10M gas worth).
test_memory_expansion_with_calldata	state_test	3	Test memory expansion gas is counted in execution_gas not floor.
test_delegatecall_no_additional_floor_cost	state_test	1	Verify DELEGATECALL operations don't trigger additional floor costs.
test_nested_call_no_additional_floor_cost	state_test	1	Verify only the transaction's calldata affects floor cost.
test_floor_cost_not_reduced_by_refunds	state_test	1	Verify floor cost acts as a true floor and is never reduced.
test_refund_cap_at_one_fifth	state_test	1	Test that refunds are capped at the fork max refund quotient.
test_token_calculation_verification	state_test	6	Verify token calculation is correct for different byte compositions.
