Remove caching from the catalog, types, and parameters

Types and parameters were registering their catalog as their expirer, so that
the catalog could expire them between uses. However, because catalogs are never
reused (and neither are types or parameters), there is no need to expire
anything. Thus, we remove the entire cleanup/expire logic from catalog, type,
and parameter.
