WinRT: Add camera button events on Windows Phone

Windows Phone 8.1 provides access to the camera button and press/release
events get passed as Key_CameraFocus and Key_Camera. Unfortunately a
release does not provide what has been pressed before, hence this
information needs to be cached when the press happens.
