[mediacapture-main] Redefine groupId to be more narrow and useful (#899)

jan-ivar has just created a new issue for https://github.com/w3c/mediacapture-main:

== Redefine groupId to be more narrow and useful ==
The undisputed use case for [groupId](https://w3c.github.io/mediacapture-main/#dom-mediadeviceinfo-groupid) is to find devices a user might want to use together in a video call. E.g. [headset switching](https://jsfiddle.net/jib1/yvj4narc/).

But the current definition: _"Two devices have the same group identifier if they belong to the same physical device"_, is too broad.

Because on linux, Firefox exposes virtual microphones from monitored output devices, with matching groupId (behind a pref). But using these together (in a video call or anywhere else) would always be a mistake as it short-circuits.

I propose we redefine it to: _"Two devices have the same group identifier if they belong to the same physical device, and are useful together in a video conferencing call."_

Happy to bikeshed.
