This provides a Model base class in Python and sub-classes of that can be set as data models in slint. The ListModel is provided as basic sub-class operating on a list() and allowing mutation and notifying the view on the Slint side. Similarly, an array declared in Slint is exposed as an object to Python that looks like a Model. Both support the sequence protocol. Fixes #4135
