Subject: [PATCH] Database: Add support for `SET STATEMENT` in
 `wpdb::get_table_from_query()`.

MariaDB supports setting various parameters for queries. This commit ensures that `wpdb` can properly retrieve the table name from such queries.

Reference: [https://mariadb.com/docs/server/reference/sql-statements/administrative-sql-statements/set-commands/set-statement MariaDB Documentation: SET STATEMENT].

Follow-up to [30345].

Props dd32.
Fixes #63777.
