migrate to nodejs's native iterator API when napi-rs is ready

[suyanhanx]

We rely heavily on napi-rs to implement our functions.

The following APIs are still in some sort of simulation and will be migrated to the native implementation when napi-rs is ready.

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol/iterator
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol/asyncIterator

Is there an issue on the napi-rs side? We can link to this page to let them know that we have a demand for this feature.

Updated with current napi-rs's RFC 3.0.

I'll handle this.

Plan to implement the System.iterator on the js side. Close this issue now.
