Anders Carlsson 7dad255ce1 Update output pixel format when starting video capture on iOS.
Update the output pixel format to the client supplied format when
starting camera capture.

Also add a new API method to get the preferred output pixel format
according to the
AVCaptureVideoDataOutput#availableVideoCVPixelFormatTypes method and
use it in AppRTCMobile.
