* Import Wasmtime support from the `wit-bindgen` repo This commit imports the `wit-bindgen-gen-host-wasmtime-rust` crate from the `wit-bindgen` repository into the upstream Wasmtime repository. I've chosen to not import the full history here since the crate is relatively small and doesn't have a ton of complexity. While the history of the crate is quite long the current iteration of the crate's history is relatively short so there's not a ton of import there anyway. The thinking is that this can now continue to evolve in-tree. * Refactor `wasmtime-component-macro` a bit Make room for a `wit_bindgen` macro to slot in. * Add initial support for a `bindgen` macro * Add tests for `wasmtime::component::bindgen!` * Improve error forgetting `async` feature * Add end-to-end tests for bindgen * Add an audit of `unicase` * Add a license to the test-helpers crate * Add vet entry for `pulldown-cmark` * Update publish script with new crate * Try to fix publish script * Update audits * Update lock file
