Expose the number of X screen through the QXcbScreenFunctions
X screen corresponds to Qt virtual desktop, and RandR output
corresponds to QScreen. There can be more than one X screen,
so we need a way to get the number of X screen for QScreen,
in particular for the right implementation of some methods
in QX11Info.
