fix(tests): align test contracts with new validation script rules

[aliersh]

This PR updates several test files to pass the new validation rules introduced in the test-validation script.

Summary of Changes

• Contract Renaming:

  • Updated contract names to match expected validation patterns (e.g., <Contract>_<Function>_Test)
  • Renamed contracts such as SystemConfig_Test to SystemConfig_SuperchainConfig_Test and fixed pluralization issues like SupportsInterfaces → SupportsInterface

• Function Name Alignment:

  • Renamed functions within test contracts to match their respective contract names (e.g., test_supportsInterfaces_succeeds → test_supportsInterface_succeeds)

• Consolidation of Test Logic:

  • Merged separate contracts into main test contracts where appropriate (e.g., consolidated L2 withdrawal tests into SequencerFeeVault_Withdraw_Test)
  • Introduced internal helper functions to reduce duplication

• Validation Script Updates:

  • Removed exclusions for test files that now follow validation rules
  • Updated comments for excluded files to reflect current validation status

LGTM; It would be nice to have a document somewhere explaining the changes and sharing it between the teams that work on contracts. (Probably in #smart-contracts in Discord)
