[remoting host] AddTrack() -> AddTransceiver()

This replaces the calls to PeerConnection::AddTrack() with
AddTransceiver(), and updates the plumbing to pass RtpTransceivers
instead of RtpSenders. Some of the newer WebRTC APIs operate on
Transceivers, and it is easier to get a Sender from a Transceiver than
it is to do the reverse. This will facilitate using the newer APIs
to migrate away from SDP-munging, and perhaps some other future uses.

There is no corresponding RemoveTransceiver() API, so the previous
cleanup code is no longer needed.

This also fixes a TODO to store the video sender (transceiver) instead
of looping over all senders (transceivers).

Tested by manually verifying video and audio are working, over multiple
connect/disconnect cycles. Also verified audio is still received at
roughly 160kbps (20k bytes/s).
