[ddc] Unify pkg:js types and allow subtyping between them

Removes the lazy loading of the underlying type in LazyJSTypes.
As such, this removes the need to keep AnonymousJSType and
LazyJSType separate, and is therefore refactored to
PackageJSType. Similarly, subtyping is fixed such that
PackageJSTypes are all subtypes of each other.
