[gtk/wip/matthiasc/popup5: 145/187] Work toward dropping widget->surface

[Matthias Clasen <matthiasc src gnome org>]

commit fbe85c3f57a264cdeb0669f14bbb9e1eff335dc7

    Work toward dropping widget->surface
    
    Drop special-casing of GtkNative in
    most widget vfuncs. GtkNative implementations
    need to override these anyway.
