Reduce type parameters and associated types' dependence on "getProtocols()".

Browse Source 
This is a step toward weeding out the "getProtocols()" list on
TypeDecl. Now, use the Archetype's list of protocols for the set of
protocols to which the type parameter or associated type
conforms. Since that list is fully canonicalized, it's more generally
reliable. However, start serializing the list of inherited types for a
generic type parameter, so we can print it appropriately.
