Move VideoDecoder::Create() logic to separate internal video decoder factory
The goal with this CL is to move implementation details out from the
webrtc root (webrtc/video_decoder.h) to simplify the dependency graph.
Another goal is to streamline the creation of VideoDecoders in
webrtcvideoengine2.cc; it will now have two factories of the same
WebRtcVideoDecoderFactory type, one internal and one external.
Specifically, this CL:
* Removes webrtc::VideoDecoder::DecoderType and use webrtc::VideoCodecType
instead.
* Removes 'static VideoDecoder* Create(DecoderType codec_type)' and
moves the create function to the internal decoder factory instead.
* Removes video_decoder.cc. webrtc::VideoDecoder is now just an
interface without any static functions.
