Make CroppingWindowCapturer respect detect_updated_region on Windows

Browse Source 
This change makes CroppingWindowCapturer::CreateCapturer respect the
detect_updated_region flag if set in the options it's passed on Windows.
Frames captured by the created capturer will now make changes available
via DesktopFrame.updated_region().
