[mediacapture-depth] Integration with Permission API

dontcallmedom has just created a new issue for 
https://github.com/w3c/mediacapture-depth:

== Integration with Permission API ==
The Media Capture and Streams spec has a pending pull request to 
integrate with the permission API; the latest draft of the Permission 
API describes [permissions for "cameras, 
microphones"](https://w3c.github.io/permissions/#media-devices).

I assume the permission for access to a depth map can be encompassed 
as part of the "camera" permissions; but that's probably worth 
clarifying both in this spec and possibly in the permissions API as 
well.
