MDEV-35617: DROP USER should leave no active session for that user

Browse Source 
DROP USER looks for sessions by the do-be-dropped user and if found:
* fails with ER_CANNOT_USER in Oracle mode
* continues with ER_ACTIVE_CONNECTIONS_FOR_USER_TO_DROP warning otherwise

Every user being dropped is marked with flag that disallow establishing
a new connections on behalf this user.
