[gtk/matthiasc/surface-state-rework: 39/80] gdk/wayland: Always configured size when resizing

    gdk/wayland: Always configured size when resizing
    
    GTK4 doesn't support arbitrary constraints when resizing a window (e.g.
    steps, or aspect ratio), so we don't need to care about the result from
    compute-size when doing interactive resizing.
