New macOS screen-capturer which uses ScreenCaptureKit.

This supports:
* Full-screen capture from any display, via SelectSource().
* Changing the display, via SelectSource(), while capture is running.
* Handling screen-resolution changes while capture is running.
* Capturing from high-DPI displays at their native resolution.
* Basic damage-tracking: the frame's updated-region is either set to
  empty, or the full frame area.

It currently does not support:
* Window capture.
* Excluded windows.
* Full-desktop capture across all displays.
* More detailed damage-tracking.

The capturer is not yet enabled. Followup CLs will add a
DesktopCaptureOption to enable this capturer on supported versions of
macOS.

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

See here for instructions on how to get started developing with the native code.
