Propertly ignore ``Identity`` in MySQL and MariaDb.
Ensure that the MySQL and MariaDB dialect ignore the
:class:`_sql.Identity` construct while rendering the
``AUTO_INCREMENT`` keyword in a create table.
The Oracle and PostgreSQL compiler was updated to not render
:class:`_sql.Identity` if the database version does not support it
(Oracle < 12 and PostgreSQL < 10). Previously it was rendered regardless
of the database version.
Fixes: #6338
