Notifies all users of the filter that it has changed.
This emits the [signal@Gtk.Filter::changed] signal. Users of the filter should then check items again via [method@Gtk.Filter.match].
Depending on the @change parameter, not all items need to be changed, but only some. Refer to the [enum@Gtk.FilterChange] documentation for details.
This function is intended for implementors of GtkFilter subclasses and should not be called from other functions.
