Update wit-bindgen and wasm-tools. (#266)

* Update wit-bindgen and wasm-tools.

The two code changes are:
 - The float32->f32 renaming.
 - wit-bindgen-rt now provides a re-export of the bitflags crate,
   so that users don't need to separately depend on bitflags.

* Update wit-bindgen-rt in the example.

* Update Wasmtime, actions/checkout, mozilla-actions/sccache-action in CI.
