Down-level logging in the WasiPreview1

Fix #534

As a follow up, we could generate these automatically in the annotation processor

I’d like to have output like strace where it prints the call and result all on one line. That would be ugly to do in the code, but easy with a generated wrapper. It needs try/catch so that we can log the call without the result when an exception is thrown.

For the result, we’d like the log to print the enum, so we’d need a way to declare the conversion from enum to WASI result type.

And even better, we could have exception mapping support, similar to JAX-RS, so that we could throw exceptions from WASI. That would allow some cleanup of the code, which is difficult now with direct return of errors. But this might be over-engineering.

@electrum agreed, let me work a little more on the annotation processors before proposing this change if you don't mind 🙏

Sure, I'm in no hurry to work on this, currently focused on AOT.
