This implementation has the function execute a request to scan the inheritance clause of non-protocol nominals for a `~Copyable`. For protocols, we look in the requirement signature. This isn't our final state, as the GenericEnvironment needs to be queried in general to determine of a Type is noncopyable. So for now checking for a `~Copyable` only makes sense for Decls.
