Make the new jitter buffer the default jitter buffer.

Browse Source 
This CL contains only the changes necessary to make the switch to the new jitter
buffer, clean up will be done in follow up CLs.

In this CL:
 - Removed the WebRTC-NewVideoJitterBuffer experiment and made the
   new video jitter buffer the default one.
 - Moved WebRTC.Video.KeyFramesReceivedInPermille and
   WebRTC.Video.JitterBufferDelayInMs to the ReceiveStatisticsProxy.
