The change at 27ba8fce6c (to fix https://github.com/Dart-Code/Dart-Code/issues/4217) added type arguments to the LSP Type Hierarchy (before, neither type args or type params were shown).
Showing type arguments seemed reasonable when looking at supertypes, but behaves oddly for subtypes (and also when invoked on a type with arguments), so this partly reverts that and shows type parameters in all cases instead.
This simplified the code a bit and removed the `TypeHierarchyAnchor` class we were round-tripping in order to preserve the type arguments.
