feat: generate java files for extended_operations.proto (#200)

feat: generate java files for error_reason.proto and localized_text.proto

BigqueryAuditMetadata is being explicitly removed because it is introducing a [circular dependency](https://paste.googleplex.com/5113053075996672) with iam.Policy.
common-protos cannot depend on iam because iam depends on common protos.
This issue needs to be resolved before BigqueryAuditMetadata can be added to the java-common-protos
