Update Wasmtime and Wizer

[jeffcharles]

Description of the change

Updates Wasmtime and Wizer.

The Wizer changes are fairly invasive since the public interface changed substantially. The big one is run became async so all callers need to become async. Alternatively we could create our own Tokio runtime and use that to make the APIs sync but that's less than ideal if a caller is already using an async runtime anyway and it's easy enough to propagate the async changes up to the main methods. The other change is Wizer's run now takes a Store<T> so we can set up the WASI context ahead of time and avoid needing to use statics to propagate input values.

Why am I making this change?

We should keep Wasmtime and Wizer up-to-date.
