Rollup merge of #44273 - bluss:rc-downcast, r=alexcrichton
Implement <Rc<Any>>::downcast * Implement `<Rc<Any>>::downcast::<T>` * New unstable method. Works just like Box\<Any\>, but for Rc. * Any has two cases for its methods: Any and Any + Send; Rc is never Send, so that case is skipped for Rc. * Motivation for being a method with self is to match Box and there is no user-supplied type; the inner type is Any and downcast does not conflict with any method of Any. * Arc was skipped because Any itself has no downcast for the case that makes most sense: Any + Send + Sync
