Previously, senders and receivers to different kinds of event loops (the main `ScriptThread`, different types of workers) used a rust `trait` mechanism to implement dynamic behavior. This led to having many unused implementations of this `trait`. This change moves to using an `enum` based approach for these senders and receivers and removes all of the dead code. In addition, to allowing for use of rust's dead code detection, it simplifies the code a great deal. All of these generic senders and receivers are moved to the `messaging.rs` file and given proper documentation. Finally, empty an `JSTraceable` implementation is made for all crossbeam `Sender<...>`s to avoid having to manually skip them everytime they are included in structs. The pre-existing empty `MallocSizeOf` implementation is used more thoroughly. Other unecessary wrappers around these senders and receivers are removed as well.
