[PATCH 4/9] user32: Add support for RIDEV_INPUTSINK flag in RegisterRawInputDevices.

[Rémi Bernon]

This flag allows applications to receive rawinput messages while in
background. They have to specify a target hwnd in which queue to receive
them and the messages will carry a RIM_INPUTSINK wparam in this case.
