Adds a field to EncoderInfo called preferred_pixel_formats which a software encoder populates with the pixel formats it supports. When a kNative frame is received for encoding, the VideoStreamEncoder will first try to get a frame that is accessible by the software encoder in that pixel format from the kNative frame. If this fails it will fallback to converting the frame using ToI420. This minimizes the number of conversions made in the case that the encoder supports the pixel format of the native buffer or where conversion can be accelerated. For example, in Chromium, the capturer can emit an NV12 frame, which can be consumed by libvpx which supports NV12. Testing: Tested in Chrome with media::VideoFrame adapters.
