Add a unique id to InternalClass that describes it's total state

So far the InternalClass only did describe the state of the class
itself, but it wouldn't change if some of the underlying
objects in the prototype chain changed. This now fixes that and
introduces a unique ID that completely describes the state of
the object including all it's prototypes.

This opens up for optimizing lookups down to one branch and a
load, independent of the depth of the value inside the prototype
chain.
