* wiggle: no longer need to guard wasmtime integration behind a feature
this existed so we could use wiggle in lucet, but lucet is long EOL
* replace wiggle::Trap with wiggle::wasmtime_crate::Trap
* wiggle tests: unwrap traps because we cant assert_eq on them
* wasi-common: emit a wasmtime::Trap instead of a wiggle::Trap
formally add a dependency on wasmtime here to make it obvious, though
we do now have a transitive one via wiggle no matter what (and therefore
can get rid of the default-features=false on the wiggle dep)
* wasi-nn: use wasmtime::Trap instead of wiggle::Trap
there's no way the implementation of this func is actually
a good idea, it will panic the host process on any error,
but I'll ask @mtr to fix that
* wiggle test-helpers examples: fixes
* wasi-common cant cross compile to wasm32-unknown-emscripten anymore
this was originally for the WASI polyfill for web targets. Those days
are way behind us now.
* wasmtime wont compile for armv7-unknown-linux-gnueabihf either
Implement Wasmtime's new API as designed by RFC 11. This is quite a large commit which has had lots of discussion externally, so for more information it's best to read the RFC thread and the PR thread.
* Enhance wiggle to generate its UserErrorConverstion trait with a function that returns
a Result<abi_err, String>. This enhancement allows hostcall implementations using wiggle
to return an actionable error to the instance (the abi_err) or to terminate the instance
using the String as fatal error information.

* Enhance the wiggle/wasmtime integration to leverage new work in ab7e9c6. Hostcall
implementations generated by wiggle now return an Result<abi_error, Trap>. As a
result, hostcalls experiencing fatal errors may trap, thereby terminating the
wasmtime instance. This enhancement has been performed for both wasi snapshot1
and wasi snapshot0.
* Update wasi-nn crate to reflect enhancement in issue #2418.
* Update wiggle test-helpers for wiggle enhancement made in issue #2418.
* Address PR feedback; omit verbose return statement.
* Address PR feedback; manually format within a proc macro.
* Address PR feedback; manually format proc macro.
* Restore return statements to wasi.rs.
* Restore return statements in funcs.rs.
* Address PR feedback; omit TODO and fix formatting.
* Ok-wrap error type in assert statement.
* Shuffle around the wiggle crates
This commit reorganizes the wiggle crates slightly by performing the
following transforms:
* The `crates/wiggle` crate, previously named `wiggle`, was moved to
`crates/wiggle/crates/macro` and is renamed to `wiggle-macro`.
* The `crates/wiggle/crates/runtime` crate, previously named
`wiggle-runtime`, was moved to `crates/wiggle` and is renamed to
`wiggle`.
* The new `wiggle` crate depends on `wiggle-macro` and reexports the macro.
The goal here is that consumers only deal with the `wiggle` crate
itself. No more crates depend on `wiggle-runtime` and all dependencies
are entirely on just the `wiggle` crate.
* Remove the `crates/wiggle/crates` directory
Move everything into `crates/wiggle` directly, like `wasi-common`
* Add wiggle-macro to test-all script
* Fixup a test
