Render media files in the CanvasContentTray

The files are there, though the visuals are incorrect. I just
lifted the documents Link component to get them displayed.
Rendering per the design will be a later ticket

closes COREFE-40

test plan:
  - load the rce in a course as a teacher
  - select Media > Course Media
  > expect course audio and video files displayed in the tray
  - switch to My Files
  > expect user audio and video files in the tray
  > expect the files to have their respective icons

  - load the rce in a course as a student
  - select Media > My Media (expect it to be the only option)
  > expect the students media files to be diplayed in the tray
  > expect Course Files not to be an option
