Code Review
This pull request introduces support for discovering and querying Property Graphs and related metadata in DatabaseMetaData methods, controlled by a new connection property EnableGraphMetadata. The changes span across BigQueryConnection, BigQueryDatabaseMetaData, DataSource, and related classes, along with new SQL resources and comprehensive tests. Feedback on the changes highlights a critical bug in getColumnTypeInfoForTypeKind where the ARRAY type kind is no longer handled, a regression in getExportedKeys where null catalog or schema arguments will trigger validation exceptions contrary to the JDBC spec, and a minor typo in a log message.
