performance: all parent classes should be be cached when calling TypeFactory.get(Class)

We do not cache properly the shadowed elements.
We only cache the top level class.

For example, `TypeFactory.get(ArrayList.class)` will cache the shadow of ArrayList but the parent classes `List.class`, `Serializable.class`, `Object.class` as will as all the used types in return value and parameters will not be cached.
This can causes performance issue when the shadow is heavily used.
