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.
