Accessing JS objects can be trapped with proxy handlers. These
handlers can throw when no node-api errors occur. In such cases,
napi_pending_exception should be returned.

We discussed in the meeting today. We already have some similar callsites which are returning the exception correctly and therefore should already be handling the way the status code will be returned after the update.

@legendecas suggested that we run CITGM as well to gather some more info.

Yes, I'm trying to reproduce it locally with an arm Linux setup.

The debug test failure is caused by the fact that v8::Object::DefineProperty didn't clear the pending exception and v8::internal::Isolate::has_pending_exception() still returned true after the v8 API call returned. This can be fixed by https://chromium-review.googlesource.com/c/v8/v8/+/4594617.

The problem can happen whenever v8::Object::DefineProperty is called on a throwing JSProxy trap handler and invokes another V8 API (but only crashes on debug build).

@nodejs/node-api CI has passed. Would you mind taking a look at this again? Thank you!

As discussed at node-api meeting Oct 20, the change is essentially a clean rebase so I'm going to land this.

This depends on 17a74dd which is included in v21.x.
