Original issue's description:
> RELAND: ImageCapture: Implement takePhoto() for Mac AVFoundation
>
> Got reverted due to breaking
> WebRtcWebcamBrowserTests/WebRtcWebcamBrowserTest.MANUAL_TestAcquiringAndReacquiringWebcam/0
> in some WebRtc Mac bot, possibly because it has no real WebCam
> or it has one without  AVCaptureStillImageOutputClass support.

> Also adding VideoCaptureDeviceTest::MAYBE_TakePhoto
> test case, enabled only for Mac.
