feat(attestation): add support for individual attesters in bulk attest and replace functions

[jukeboxhero123]

What does this PR do?

Modifies the Abstract Portal contract so that the getAttester() function takes in the attestation and validation payloads as parameters. This adds more flexibility allowing for signature-based patterns much cleaner. Additionally, this PR modifies how ModulesRegistry and AttestationRegistry handle bulk attests with a new function that takes in an array of attesters. Backwards compatibility is maintained.

Note

Adds per-attestation attester support across bulk flows and updates attester resolution in portals.

• Registries:
  • AttestationRegistry: new bulkAttestWithAttesters and bulkReplaceWithAttesters; validates array lengths; existing bulk methods retained.
  • ModuleRegistry: new bulkRunModulesV2WithAttesters to pass attesters per payload; adds ArrayLengthMismatch error.
• Portal:
  • AbstractPortalV2: getAttester now takes attestationPayload and validationPayloads; single and bulk operations compute attesters and call new registry methods; _onReplace updated to receive computed attester.
• Tests/Mocks:
  • Mocks extended with new bulk-per-attester methods and events for compatibility.
