[Studio] Prevent videos from importing to another course without the creator's permission.

Problem statement:

We have many teachers who spend a lot of time and energy creating Canvas Studio videos for their course. But sometimes they need to share the shell with another teacher who is providing secondary instruction in the course. Teachers/Creators need to be able to prevent other instructors in the shell from snatching those videos by either downloading them or copying/importing them into other shells, or sandboxes.

Proposed solution:

Create an option for the teacher to see and decide what course shells have access to these videos (and maybe more importantly which don't have access).
