Remove license from course outline page in Studio

This allows course authors to choose between two difference licenses for their
course content: All Rights Reserved, or Creative Commons. In the backend, XBlocks
that wish to allow custom licenses need only inherit from LicenseMixin, which
adds a `license` field as a string.

License information is displayed in the Studio editor view, and just below the
rendered XBlock in the LMS. In addition, if the course block itself has a custom
license set, this license will display just below the main body of the page
on courseware pages.

This entire feature is gated behind the LICENSING feature flag.

But mark `data` as non-editable metadata, so that it doesn't appear

This will make it easier to add the creation and update interfaces.

The checks are now within the Python API instead of the DRF view. This
will be necessary for certain operations (like fetching/editing threads)
because the relevant course cannot be known until the thread is fetched
from the comments service. This commit updates the existing endpoints to
fit that pattern.
