perkj 267527459b Remove cricket::VideoCodec with, height and framerate properties 
Since WebRtcVideoSendStream have reconfigures the send codec to match the incoming captured frames widht and height they have not been used.
Framerate has just been set when parsing sdp to 60fps and not changed elsewhere.

This cl require some upstream projects to change first.
