Expose async_wrap providers

[RafaelGSS]

Once process.binding was considered deprecated(v16+), we don't have a public API (AFAIK) to access the process.binding(async_wrap).Providers.

At node-clinic we use it to correlate with stack-traces, is there anything that replaces that information?

I think you can create a new property inside a async_hooks and expose this using a public API.

Could you send a PR?

PR created.

Just for reference, I've found #37575 that discuss the same approach.
