MDEV-36996: Implement INFORMATION_SCHEMA.TRIGGERED_UPDATE_COLUMNS table

Browse Source 
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.
