Add is_disconnected functions to mpsc and mpmc channels Add `is_disconnected()` functions to the `Sender` and `Receiver` of both `mpmc` an `mpsc` channels. ```rust std::sync::mpmc::Sender<T>::is_disconnected(&self) -> bool std::sync::mpmc::Receiver<T>::is_disconnected(&self) -> bool std::sync::mpsc::Sender<T>::is_disconnected(&self) -> bool std::sync::mpsc::Receiver<T>::is_disconnected(&self) -> bool ``` The `mpsc` methods are locked behind the `mpsc_is_disconnected` feature gate, which has no tracking issue yet.
