Stop using hardcoded payload types for video codecs

This CL stops using hardcoded payload types for different video codecs
and will dynamically assign them payload types incrementally from 96 to
127 instead.

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.
