MDEV-29668 SUPER should not allow actions that have fine-grained dedicated privileges

SUPER privilege used to allow various actions that were alternatively
allowed by one of BINLOG ADMIN, BINLOG MONITOR, BINLOG REPLAY,
CONNECTION ADMIN, FEDERATED ADMIN, REPL MASTER ADMIN, REPL SLAVE ADMIN,
SET USER, SLAVE MONITOR.

Now SUPER no longer does that, one has to grant one of the fine-grained
privileges above to be to perform corresponding actions.

On upgrade from MariaDB versions 10.11 and below all the privileges
above are granted automatically if the user has SUPER.

As a side-effect, such an upgrade will allow SUPER-user to run SHOW
BINLOG EVENTS, SHOW RELAYLOG EVENTS, SHOW SLAVE HOSTS, even if he wasn't
able to do it before the upgrade.
