[mediacapture-main] Closed Pull Request: Add pre-grant deviceId alternative.

jan-ivar has just closed pull request 373 for 
https://github.com/w3c/mediacapture-main:

== Add pre-grant deviceId alternative. ==
Tries to capture the alternative we discussed at the last virtual 
face-to-face.

With all this info, I reordered the text a bit to cover uniqueness, 
stability, pre-grant behavior, and cookies in that order. I also:

 * Tried to clarify that ids persist after allowing gum just once.
 * Added visible cookie requirement to the UA alternative.
 * Tried to fix clearing logic to not orphan same-origin tabs (clear 
when last origin tab closes).
 * Restrict persistence for sites blocked from using cookies.
