deps: add v8::Object::SetInternalFieldForNodeCore()

This is a non-ABI breaking solution added by Node.js in v20.x for:

* https://chromium-review.googlesource.com/c/v8/v8/+/4827307
* https://chromium-review.googlesource.com/c/v8/v8/+/4707972

which are necessary for backporting the vm-related memory fixes in nodejs/node#48510.
