In preparation for switching LMS/Studio over
from serving legacy courseware URLs in certain
places (for example, resume_course_url) to serving
learning micro-frontend URLs.

* Install `organizations` app into LMS and Studio non-optionally.
* Add toggle `ORGANIZATIONS_AUTOCREATE` to Studio.
* Remove the `FEATURES["ORGANIZATIONS_APP"]` toggle.
* Use the new `organizations.api.ensure_organization` function to
either validate or get-or-create organizations, depending
on the value of `ORGANIZATIONS_AUTOCREATE`,
when creating course runs and V2 content libraries.
We'll soon use it for V1 content libraries as well.
* Remove the `util.organizations_helpers` wrapper layer
that had to exist because `organizations` was an optional app.
* Add `.get_library_keys()` method to the Split modulestore.
* Add Studio management command for backfilling organizations tables
(`backfill_orgs_and_org_courses`).
