Hmm, #93044 got closed, so I guess I should reopen this. |

@Dylan-DPC What exactly should I change here? I could obviously rebase my PR every half a year while it waits for reviews, but that's just busy work. It'd be nice if this could get reviewed before I rebase it. |

Add `Read`, `Write` and `Seek` impls for `Arc<File>` where appropriate If `&T` implements these traits, `Arc<T>` has no reason not to do so either. This is useful for operating system handles like `File` or `TcpStream` which don't need a mutable reference to implement these traits. CC rust-lang#53835. CC rust-lang#94744.
