winex11.drv: Add Xinerama display device handler.
Display device handlers are used to initialize the display device
registry data. Different handlers can be implemented according to
the defined interface, for example, via Xinerama or XRandR.
With those registry data, EnumDisplayDevices, EnumDisplayMonitors
and GetMonitorInfo can be built on top of it.
