Respond to the _NET_WM_CONTEXT_HELP WM_PROTOCOLS message
This change restores a proper function of the "(?)" button in the window
decorations which is used as a clue for the user to check what a particular
widget is supposed to do. The change is only implemented for QtWidgets because
the underlying QWhatsThis is inherently widget-specific -- which is why it sends
an event to QGuiApplication, but only processes it in the QtWidget-specific
QApplication.
Thanks to Alberto Mardegan and Gunnar Sletta for their feedback on this patch.
