Emit DROP CHECK for MySQL, DROP CONSTRAINT for MariaDB

Added support for MySQL "DROP CHECK", which is added as of MySQL 8.0.16,
separate from MariaDB's "DROP CONSTRAINT" for CHECK constraints.  The MySQL
Alembic implementation now checks for "MariaDB" in server_version_info to
decide which one to use.

Fixes: #554
