feat: removing djangoapp demographics, step 1 (#35182)

* feat: removing djangoapp `demographics`, step 1

This step removes the models, the references to the models, and adds a
migration to drop both tables  (`HistoricalUserDemographics`  didn't
have a corresponding model but was still a valid table).

Once this has deployed, this will be removed from `INSTALLED_APPS` and
completely removed.

No other apps  in the repository currently reference this djangoapp  in
code or tables.

FIXES: APER-3560
