Add field VideoEncoderConfig::codec_type.

Browse Source 
First step of the transition needed to reland cl
https://webrtc-review.googlesource.com/62062, and move payload_name
and payload_type out of VideoSendStream::Config::EncoderSettings.

If the new field is set to something different than kVideoCodecUnkown,
payload_name from EncoderSettings is ignored.
