With tokio-rs#6779 we removed unnecessary allocations from the timerwheel by wrapping it in an `std::sync::RwLock`. Since the `Mutex` used in this part of the project uses an abstraction in `loom::sync::Mutex` to get rid of the poisoning aspects of `std::sync::Mutex` the same should probably be done for the used read-write lock struct. This commit introduces an abstraction to get rid of the poisoning aspects of `std::sync::RwLock` by introducing a wrapper to the `loom::sync` module similar to `loom::sync::Mutex`.
