All code in this PR should be removed after REVE-52 is merged and mobile
traffic from older app versions falls to < 5% of the mobile traffic
to the course_blocks api
This is based on PR #19284 and is part of the
series of work related to the proposal #18134.
Adds VideoModule.public_view() to enable
unenrolled and anonymous users to view the video
contents of a public course.
When an unenrolled or anonymous user accesses the
video content of a public course, the
public_view() introduced in the previous PR is
used instead of student_view() method.
The course_visiblity field can have one of three values:
1. private (default): This keeps the standard access rules.
2. public_outline: Allows unenrolled and anonymous users access to the outline.
3. public: Allows unenrolled and anonymous users access to both outline and
course content.
When an unenrolled user accesses course content, instead of student_view(),
public_view() is used. A default implementation is provided for XBlocks
which do not implement this view. The public_view() must not have any
functionality which assumes the presence of a valid User and should show
a readonly only interface for the XBlock content.

Content Type Gating: Xblocks that have a graded component cannot be
accessed by audit track users.
- Caveats:
- In studio, instructors can set certain xblocks to be available to
all users, but graded components will default to not being
available for audit users
- If a course does not have a verified mode option, all users will
have access to graded content.
The Waffle Flag: The waffle flag is of for now.
It's name is: ```content_type_gating.debug```
This Commit Does NOT Include: Displaying for a user WHY they do not have
access to a specific piece of content. That change will be part of
another PR.
