MDEV-36996: Implement INFORMATION_SCHEMA.TRIGGERED_UPDATE_COLUMNS table
MariaDB 11.8 and above allows to specify list of columns in the update trigger and such trigger is fired only when one of the specified columns is updated. The `INFORMATION_SCHEMA.TRIGGERED_UPDATE_COLUMNS` table lists all such columns for a trigger. A column is shown only if the user has any non-SELECT privileges on the column specified in the trigger.
