Remove VCMEncodedFrame from the inheritance chain of EncodedFrames by - moving getters for EncodedImage fields up to EncodedImage - copying other non-deprecated fields & Methods from VCMEncodedFrame over to EncodedFrame - Removing EncodedFrame's inheritance of VCMEncodedFrame We leave VCMEncodedFrame as part of the (near) deprecated VideoCodingModule code. The only place which needs to accept either is in the generic decoder.
