    gdkcursor-win32.c: Add cursor map for all-scroll
    
    This makes sure that we don't have cursors disappearing on Windows upon
    scrolling because we can't find a cursor that exists on the system during
    a scroll, and unlike GTK-3.x, we do not default to the arrow pointer on GTK4.
    
    Just mimic what we have on X11 and Wayland: the trusty standard arrow pointer.
    
    Fixes issue #3581.
