Re: [mediacapture-screen-share] Is it meaningful to select window audio to be system or window at surface selection time? (#325)

> The web app will not know whether receiving system vs. window audio

I think it would be good to expose [displaySurface](https://www.w3.org/TR/screen-capture/#dfn-displaysurface) on audio tracks as well, exactly for that purpose. If there's general support for this, either @drkron or I could prepare a PR.

Chrome does not currently plan to provide such UX, but I'm happy to support whichever spec changes would help Safari provide a fuller solution here. For example, maybe such a change should fire a [configurationchange](https://w3c.github.io/mediacapture-extensions/#dom-mediastreamtrack-onconfigurationchange) event.
