This helper is used by the LMS, CMS, _and_ `openedx.core`,
so let's move it to `openedx.core` to reduce import complexity.
The following files no longer import from LMS:
- cms/djangoapps/contentstore/management/commands/edit_course_tabs.py
- lms/djangoapps/ccx/migrations/0006_set_display_name_as_override.py
- openedx/core/djangoapps/ccxcon/api.py
- openedx/core/djangoapps/verified_track_content/models.py
- openedx/features/course_experience/plugins.py
Note: The LTI XBlock has a dependency on this import path (!?);
a fix can be found here [1].
