WKWebView should provide a way for clients to know the specific media state.

[Andrew Gold]

Currently, WKUIDelegate methods are called when a WKWebView begins/ends a capture session. Now, clients must know which specific devices are being used (microphone, camera, or both).

Isn't this just `if (oldMediaStateHasActiveCapture != newMediaStateHasActiveCapture)`?

No, because the MediaState may change for reasons other than a capture session beginning or ending (such as when audio/video starts playing).

I'm sorry, I misread this comment. You're right, that is the same. Will make this change, along with some others Alex and I discussed offline.
