MDL-76974 user: deprecate old method of setting user preferences.
The `M.util.set_user_preference` method (plus accompanying helpers)
are now deprecated, in favour of the `core_user/repository` module
to achieve the same.

Update current implementation to proxy calls to the new API ensuring
backwards compatibility, while emitting copious developer debugging.
