* wasi-common: update wasi submodule This updates the WASI submodule, pulling in changes to the witx crate, now that there is a 0.9.1 version including some bug fixes. See WebAssembly/WASI#434 for more information. * wiggle: update witx dependencies * publish: verify and vendor witx-cli * adjust root workspace members This commit removes some items from the root manifest's workspace members array, and adds `witx-cli` to the root `workspace.exclude` array. The motivation for this stems from a cargo bug described in rust-lang/cargo#6745: `workspace.exclude` does not work if it is nested under a `workspace.members` path. See WebAssembly/WASI#438 for the underlying change to the WASI submodule which reorganized the `witx-cli` crate, and WebAssembly/WASI#398 for the original PR introducing `witx-cli`. See [this comment](https://github.com/bytecodealliance/wasmtime/pull/3025#issuecomment-867741175) for more details about the compilation errors, and failed alternative approaches that necessitated this change. N.B. This is not a functional change, these crates are still implicitly workspace members as transitive dependencies, but this will allow us to side-step the aforementioned cargo bug.

wiggle
Wiggle is a code generator for the host side of a witx interface. It is
invoked as a Rust procedural macro.
Wiggle is not specialized to any particular WebAssembly runtime. It is usable in at least Wasmtime and Lucet.
Learning more
Read the docs on docs.rs.
There are child crates for integrating with Wasmtime and Lucet.
The wasi-common crate is implemented using Wiggle and the wasmtime-wasi crate integrates wasi-common with the Wasmtime engine.
Andrew Brown wrote a great blog post on using Wiggle with Wasmtime.
