This CL is the step 1 for adding alpha channel support over the wire in webrtc. - Add the footprint for adapter classes that wraps actual codecs. - This CL does not add a webrtc::VideoFrame container that can carry alpha to make the CL shorter for an easier review. Therefore, it exercises a code path for when we receive no alpha input, just regular I420 frames. - Unittest sends a video frame for encode/decode through these adapters and checks the output PSNR. - See https://webrtc-review.googlesource.com/c/src/+/7800 for the experimental CL that gives an idea about how it will come together.
