Introduce a new method I420Buffer::CropAndScale, and a static convenience helper I420Buffer::CenterCropAndScale. Use them for almost all scaling needs. Delete the Scaler class and the cricket::VideoFrame::Stretch* methods. BUG=webrtc:5682 R=pbos@webrtc.org, perkj@webrtc.org, stefan@webrtc.org Review URL: https://codereview.webrtc.org/2020593002 .
