fix(ext/napi): don't close handle scopes in NAPI as the pointers are invalid (#21629)

`napi_open_handle_scope` was returning a bogus handle_scope and we were
trying to close it in `napi_close_handle_scope`.

This is a bit of a challenge to test, but the following testcase comes
from #21601 and appears to be fixed by this.

```
import { decode } from "https://deno.land/std@0.209.0/encoding/base64.ts";
import sharp from "npm:sharp";

const img = 'iVBORw0KGgoAAAANSUhEUgAAAQAAAAEAAQMAAABmvDolAAAAA1BMVEWq09/P7Lz1AAAAH0lEQVRoge3BAQ0AAADCoPdPbQ43oAAAAAAAAAAAvg0hAAABmmDh1QAAAABJRU5ErkJggg==';
Deno.test("async", async () => {
  const id = setTimeout(() => Deno.exit(1), 1000);
  await sharp(decode(img)).toBuffer();
  await sharp(decode(img)).toBuffer();
  clearTimeout(id);
});
```
