* stop linting associated types and generic type parameters * start linting ones in trait impls whose corresponding definitions in the traits are generic * remove the `is_copy` check as presumably the only purpose of it is to allow generics with `Copy` bounds as `Freeze` is internal and generics are no longer linted * remove the term 'copy' from the tests as being `Copy` no longer have meaning
