[nautilus/gtk4-preparation-trunk: 7/50] window: Drop GdkScreen parameter from ::new()




commit cae8d6015bedea11adff4b6af4f08c941a0e05bc

    window: Drop GdkScreen parameter from ::new()
    
    GdkScreen is obsolete, and gone in GTK 4. Also, most of the time it's
    just the default screen anyway.
    
    For the 2 cases where we actually want to set a display, do it
    separately using wrapers with the same signatures as the GTK 4 API.
