getUserMedia media streams should present audio tracks before video tracks
rdar://172204931

Reviewed by Eric Carlson.
Web sites, like WPT webrtc/protocol/split.https.html, often do call
RTCPeerConnection.addTrack with the order of MediaStream.getTracks.
This has an effect on the order of transceiver and on the SDP.
Chrome and Firefox always start with audio track then video track for
getUserMedia.
WebKit was not doing this as it was relying on a map of tracks.
We change to a Vector of tracks, which ensures that getUserMedia audio track
will happen before video track.
Covered by rebased WPT test and updated layout test.
