Reland of Stop using hardcoded payload types for video codecs (patchset #1 id:1 of https://codereview.webrtc.org/2513633002/ )

Reason for revert:
The WebRtcBrowserTest.NegotiateUnsupportedVideoCodec test has been fixed in Chromium with the following change:
   function removeVideoCodec(offerSdp) {
-    offerSdp = offerSdp.replace('a=rtpmap:100 VP8/90000\r\n',
-                                'a=rtpmap:100 XVP8/90000\r\n');
+    offerSdp = offerSdp.replace(/a=rtpmap:(\d+)\ VP8\/90000\r\n/,
+                                'a=rtpmap:$1 XVP8/90000\r\n');
     return offerSdp;
   }

> > This CL:
> >  * Replaces 'std::vector<VideoCodec> DefaultVideoCodecList()' in
> >    webrtcvideoengine2.cc with an explicit WebRtcVideoEncoderFactory for
> >    internally supported software codecs instead. The purpose is to
> >    streamline the payload type assignment in webrtcvideoengine2.cc which
> >    will now have two encoder factories of the same
> >    WebRtcVideoEncoderFactory type; one internal and one external.
> >  * Removes webrtc::VideoEncoder::EncoderType and use cricket::VideoCodec
> >    instead.
> >  * Removes 'static VideoEncoder* Create(EncoderType codec_type)' and
> >    moves the create function to the internal encoder factory instead.
> >  * Removes video_encoder.cc. webrtc::VideoEncoder is now just an
> >    interface without any static functions.
> >  * The function GetSupportedCodecs in webrtcvideoengine2.cc unifies
> >    the internal and external codecs and assigns them payload types
> >    incrementally from 96 to 127.
> >  * Updates webrtcvideoengine2_unittest.cc and removes assumptions about
> >    what payload types will be used.
