Re: [mediacapture-screen-share] Define and rely on "display" permission-based feature policy.

The main purpose of a display is to display stuff (facing out of the computer).
We could imagine "display" being used for "is allowed to display on the displayed surface". But it's hard to imagine a Web page without that right, so it's kind of like allowing a fish to be wet.

The permission we're mediating here is a secondary function - that of allowing the display to be scraped by the computer.

The closest permission analogy to "display" in the other direction I can think of is "speaker"; there, we mediate an outward-facing access; we never capture from a speaker.

The only reason to stick with "display" is that we're already using it, and nobody else is. I'm not greatly worried about it either way.
