[gtk: 4/8] gdk/surface: Add toplevel_resize vfunc

    gdk/surface: Add toplevel_resize vfunc
    
    To separate how toplevels and popups are configured, a first step is to
    introduce a resize-only vfunc for backends to implement. It's meant to
    only configure toplevel windows, i.e. popups. Currently it's used for
    both types, but introducing the resize-only API is a first step.
