Spring Add MariaDB to the supported database products for procedures and functions

After switching the database driver from mysql-connector-java to mariadb-java-client in one of our applications, stored procedures called with SimpleJdbcCall no longer worked and failed with an exception like java.sql.SQLSyntaxErrorException: Incorrect number of arguments for PROCEDURE foo.bar; expected 12, got 0.

After some investigation I noticed that the CallMetaDataProviderFactory has a list called supportedDatabaseProductsForProcedures (which contains MySQL, but not MariaDB) so accessProcedureColumnMetaData was set to false and initializeWithProcedureColumnMetaData was not called on the CallMetaDataProvider; thus no parameters where added to the procedure call, resulting in the SQLSyntaxErrorException.

So I think MariaDB should be added to the supportedDatabaseProductsForProcedures.

As with #24443, we're going to add this to 5.2.x (5.2.10) and also backport it to 5.1.x (5.1.19). Thanks for raising it!

As pointed out in https://github.com/spring-projects/spring-framework/commit/392ad0999076ed1158ba9139a0a71e5a298474de, we should add MariaDB to supportedDatabaseProductsForFunctions (since MySQL is also there).
