[model] Add a private row mutator to ClutterModelIter

Browse source 
When calling clutter_model_iter_next () / clutter_model_iter_prev () we need
to update the row for the iterator. In order to improve the peformance of
iterating this change adds a private row mutator and switches ClutterListModel
to use it.
