Make DefaultTrackSelector prefer more efficient video codecs (everything else being equal)

[ojw28]

If there are multiple video TrackGroups that are roughly equivalent except for the codec used, DefaultTrackSelector should prefer to select the TrackGroup that uses the most efficient codec*.

• An exception would be if a less efficient codec appears to have a hardware decoder, where-as the more efficient codec does not.

Should in theory be able to work around this by hooking up the setPreferredAudio/VideoMimeType APIs on the DefaultTrackSelector.
