Reason for revert: M80 Stable blocker bug 1046501

Original change's description:
> media: use VEA SupportedProfile |min_resolution| for PeerConnection
> 
> crrev.com/c/1828078 added and wired the video encode acceleration
> minimum resolution; this CL uses this information from peerconnection's
> rtc_video_encoder.cc and video_codec_factory.cc to avoid using a
> hw accelerator for resolutions below the given one.
> 
> TEST=https://codepen.io/miguelao/full/jONQBYb on nocturne (pixel slate), then
> inspecting chrome:webrtc-internals, verifying that resolutions below 321x241
> are encoded using libvpx while larger ones are encoded using "ExternalEncoder",
> i.e. the video encode accelerator in Chrome, in this case VA-API.
