[gtk/wip/ebassi/a11y-2: 30/31] Drop unused AtkRegistry path

    Drop unused AtkRegistry path
    
    We expect widgets to use their own derived GtkWidgetAccessible type,
    these days, and given that we hard code the default accessible type of a
    GtkWidget to GtkWidgetAccessible, and that we enforce the dependency of
    the type passed to gtk_widget_class_set_accessible_type(), the registry
    code path is clearly unused.
