alloc: Implement downcast Rc<Any> -> Rc<T>
Implement downcast the like it exists for Box. The implementation avoids using into_raw/from_raw, because the pointer arithmetic which should cancel does not seem to optimize out at the moment. Since Rc<T> is never Send, only Rc<Any> and not Rc<Any + Send> implements downcast.
