MDL-39390 delete old moodle_database column cache

With MDL-39389 all the remaining drivers have been moved
from the in-memory, per-request ::columns cache to
the MUC (databasemeta) alternative.

That makes the old cache unused, so this is, simply about to
delete it, and warn in upgrade notes for potential sites
using custom moodle_database drivers.
