Wrapper pattern is widely used in DesktopCapturer implementations. So this change adds DesktopCapturerWrapper and CaptureResultDesktopCapturerWrapper as the base classes of other wrappers. Implementing a new wrapper should become easy, the implementation does not need to care about the uninteresting overrides.
