Makes the `HintWriterClient` + `PreimageOracleClient` traits asynchronous to prevent blocking of the host program when executing a client program natively. Previously, since the preimage oracle bindings for the client were entirely synchronous, the loops in `PipeHandle` could cause a deadlock. Now that oracle IO is asynchronous, the runtime can interrupt a future when it yields execution (i.e. `tokio::select` works.) In the client program, synchronous execution is still guaranteed. It can run async colored functions in a minimal runtime, such as the `block_on` runtime in `kona_common`. `simple-revm` had to be changed as a part of this PR, which has an example of this.
Improves the asynchronous logic in `kona-host` to handle gracefully exiting the parallel host and client threads if either throw.

Overview
Improves the asynchronous logic in
kona-hostto handle gracefully exiting the parallel host and client threads if either throw.Also does a bit of cleanup in the host.
