Greatly speeds up setRemoteDescription() by moving encoder initialization off the main worker thread, which is free to move onto gathering ICE candidates and other tasks while InitEncode() is performed. It also un-blocks PeerConnection GetStats() which is no longer blocked on encoder initialization. BUG=webrtc:5410 R=stefan@webrtc.org Review URL: https://codereview.webrtc.org/1757313002 .
