Tanya L. Crenshaw b06ed39c1e Fixes #2418 : Enhance wiggle to generate its UserErrorConverstion trait with a function that returns Result<abi_err, String> (#2419 )

* 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 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.
