Mirko Bonadei 61709a3233 Revert "Begin implementing WGC CaptureFrame"
This reverts commit e820cef5340610b9beebbcb63868743b95b97fcd.

Reason for revert: Breaks downstream client. I will investigate and
get back with a suggestion to fix.

Original change's description:
> Begin implementing WGC CaptureFrame
>
> This change introduces the design that will allow us to deliver frames
> synchronously to callers despite the Windows.Graphics.Capture APIs being
> inherently asynchronous.
>
> We achieve this by having WindowCapturerWinWgc create and maintain a
> WgcCaptureSession object for each window that it is asked to capture a
> frame for. The capture session object will be the class that actually
> uses the WGC APIs, and it will store the frames it receives in a frame
> pool and deliver them via GetMostRecentFrame.
>
> The next CL will add the necessary functionality to the
> WgcCaptureSession class.
