        Discussed in #76249.

        * gtk/gtkliststore.[ch]: made gtk_list_store_remove return a gboolean,
        added gtk_list_store_iter_is_valid.

        * gtk/gtktreestore.[ch]: made gtk_tree_store_remove return a gboolean,
        added gtk_tree_store_iter_is_valid.

        * gtk/gtktreemodelsort.[ch]: added VALID_ITER macro as in liststore
        and treestore sources, added gtk_tree_model_sort_iter_is_valid.
