Implement external scaling/premapping for video

A new API allows webrtc to request the FrameBuffer to prepare for
software readback at the given resolution.
It's done asynchronously because underlying mechanism in chromium is
asynchronous and can take a long time. This way there will be no
artificial bottleneck in the pipeline.

This CL is a no-op itself, as no FrameBuffer implemnetation overrides
the `PrepareMappedBufferAsync()` yet.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
