[VM/runtime] Refactor the representation of type parameters in the VM.

This introduces a new VM internal class 'TypeParameters' representing the declaration of a list of type parameters, either in a class or function.
The reference to (or use of) a type parameter is still represented by the existing 'TypeParameter' class.
