xfree86: add xf86UpdateDesktopDimensions()

This call is required for external drivers (specifically NVIDIA) that do
not share the xfree86 infrastructure to update the desktop dimensions.
Without it, the driver would update the ScreenRecs but not update the total
dimensions the input code relies on for transformation.

This call is a thin wrapper around the already-existing internal call and
should be backported to all stable series servers, with the minor ABI bump.
