Code Review

This pull request updates several Google Cloud client libraries based on updated protobuf definitions. Key changes include the addition of the IngestAdEvents API in google-ads-datamanager, new verification APIs (VerifyReferenceList and VerifyRuleText) in google-cloud-chronicle, support for Compute Engine instances in google-cloud-confidentialcomputing attestation verification, and several new services (such as AclConfigService, CmekConfigService, LicenseConfigService, UserLicenseService, and UserStoreService) and streaming APIs in google-cloud-discoveryengine. All corresponding client files, samples, and tests have been automatically regenerated. I have no feedback to provide.
