This PR implements RefUnwindSafe for Rc<T>, where T: RefUnwindSafe.
This impl was omitted by an apparent oversight. Rc<T> already implements UnwindSafe. Arc<T> implements both UnwindSafe and RefUnwindSafe. There is no reason why an &Rc<T> is any less unwind safe than a Rc<T> or an &Arc<T>, so this should be safe to add.
Resolves #45924.
