[gtk/matthiasc/for-master] window: Drop some dead code

[Matthias Clasen <matthiasc src gnome org>]

commit 0b4817a1c6d0f1de8750fc1847cca21e47ffc044

    window: Drop some dead code
    
    The gtk_window_set_buildable_property implementation
    was only used to set the unused builder_visible flag.
    Remove both the flag and the vfunc.
    
    This means we no longer have any set_buildable_property
    implementations and could eventually drop that vfunc and
    the support for it in GtkBuilder.
