Fix #12650: "windows not receiving mouse events in multiple screens context"

	* dix/events.c, include/dix.h:
	  (UpdateSpriteForScreen): added this to update the mouse sprite context
	   when we switch from a pScreen to another.
	* mi/mipointer.c:
	  (miPointerWarpCursor): as we are switching to a new pScreen,
	   don't forget to update the mouse sprite context.
