MIPVariable: Change to a subclass of FiniteFamily

[mkoeppe]

... to give it a richer set of operations, such as len() to get the number of components and an implementation of .inverse_family() to allow looking up the key of a given component (LinearFunction instance).

This requires making AbstractFamily and FiniteFamily Cython classes.

Depends on #34839
