winex11.drv: Retrieve virtual and primary monitor rectangles from SetupAPI.

So that a process can still get the correct virtual and primary monitor rectangles if display devices are reinitialized in another process. Note that we can't use EnumDisplayMonitor() and GetMonitorInfo() here because they are not loaded when loading winex11.drv.
