Re: [mediacapture-main] Clarify whether groupId is origin-unique

Here's the trouble I have reading it: `enumerateDevices` is a global 
method, and in its [processing 
steps](https://w3c.github.io/mediacapture-main/#dom-mediadevices-enumeratedevices)
 I find no mention of origin-uniqueness, unless there is some 
definition of "browsing session" that includes origin-specific 
context. I thought it just meant "for as long as the browser is 
running".

In other words, if not for the requirement given under 
[deviceId](https://w3c.github.io/mediacapture-main/#widl-MediaDeviceInfo-deviceId),
 I think one could be forgiven for thinking the list returned was 
global.

Absent similar wording under 
[groupId](https://w3c.github.io/mediacapture-main/#widl-MediaDeviceInfo-groupId),
 it seems at least difficult to deduce that it must be origin-unique 
as well.
