Subject: [PATCH] MDL-77007 auth: Remove auth-yui-passwordunmask

This was used as part of the auth_config.php configuration system for
the auth subsystem, which was deprecated in Moodle 3.3.

It has never had any other uses in core.

Whilst it would be ideal to deprecate it by replacing with an
alternative, it would be impossible to test.
