Add a whole lot of semicolons to WIT files (#7159)

To prepare this commit I've run `WIT_REQUIRE_SEMICOLONS=1 ./ci/run-tests.sh`
locally which configures `wit-parser` to generate an error for missing
semicolons in WIT files. This led me to add quite a few semicolons in
quite a few places in what is going to be the first of a few batches of
semicolons.

CI checks for this cannot be added just yet because the wasi-nn spec is
a submodule which needs to be updated with semicolons before this
repository can require semicolons. Nevertheless that doesn't stop us
from using semicolons in the meantime (yay gradual rollout of changes!)
so I figure this would be good to get in sooner rather than later.

Update Wasmtime for upcoming WIT changes (#6390)

* Update Wasmtime for upcoming WIT changes

This PR integrates bytecodealliance/wasm-tools#1027 into Wasmtime. The
main changes here are:

* WIT syntax is updated with WebAssembly/component-model#193
* Generated bindings in the `bindgen!` macro have been updated to
reflect the new structure of WIT.
* The accepted component model binary format has been updated to account
for changes.

This PR disables wasi-http tests and the on-by-default feature because
the WIT syntax has been updated but the submodule containing the WITs
has not been updated yet so there's no way to get that building
temporarily. Once that's updated then this can be reenabled.

* Update wasmtime-wasi crate with new WIT

* Add wit-bindgen override for the updated version

* Officially disable wasi-http tests/building

* Move test-reactor WIT into the main WIT files

Don't store duplicates with the rest of the WASI WIT files we have.

* Remove adapter's copy of WIT files

* Disable default features for wit-bindgen

* Plumb disabling wasi-http tests a bit more

* Fix reactor tests and adapter build

* Remove no-longer-needed feature

* Update adapter verification script

* Back out some wasi-http hacks

* Update vet and some dependency sources

* Move where wit-bindgen comes from

Make it a more "official" location which is also less likely to be
accidentally deleted in the future.

* Don't document wasi-http-tests

Update WIT tooling used by Wasmtime (#5565)

* Update WIT tooling used by Wasmtime

This commit updates the WIT tooling, namely the wasm-tools family of
crates, with recent updates. Notably:

* bytecodealliance/wasm-tools#867
* bytecodealliance/wasm-tools#871

This updates index spaces in components and additionally bumps the
minimum required version of the component binary format to be consumed
by Wasmtime (because of the index space changes). Additionally WIT
tooling now fully supports `use`.

Note that WIT tooling doesn't, at this time, fully support packages and
depending on remotely defined WIT packages. Currently WIT still needs to
be vendored in the project. It's hoped that future work with `cargo
component` and possible integration here could make the story about
depending on remotely-defined WIT more ergonomic and streamlined.

* Fix `bindgen!` codegen tests

* Add a test for `use` paths an implement support

* Update to crates.io versions of wasm-tools

* Uncomment codegen tests

Add a `wasmtime::component::bindgen!` macro (#5317)

Add a `wasmtime::component::bindgen!` macro (#5317)

* 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
