Summary TrackInfo/MediaSamplesBlock do not allow for protected content.

TrackInfo and MediaSamplesBlock do not carry the proper information to hold encrypted content. As they are used to serialise CMSampleBuffer objects over IPC, one of the consequences is that encrypted CMSampleBuffer can't be sent over IPC. We should add support for encryption and also allows conversions of encrypted CMSampleBuffer into a MediaSamplesBlock.
