* 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
with the prev approach, it would be passed by reference sometimes
(e.g. when used as an Array argument) but by value most of the time.
this was inconsistient.
theres no need to pass the owned version, all operations are &self.
