Report queueMicrotask errors to the error event

[jasnell]

Per the queueMicrotask(...) spec... https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#microtask-queuing

globalThis.addEventListener('error', (event) => {
  console.log(event.error);
  return true;
})

queueMicrotask(() => {
  throw new Error('sync error throw in microtask');
});

The 'error' event should preserve async context in case the queueMicrotask originates from within a request:

const als = new AsyncLocalStorage();
addEventListener('error', (event) => {
  console.log(als.getStore());
});

export default {
  fetch() {
    als.run(123, () => {
      queueMicrotask(() => {
        throw new Error('boom');
      });
    });
  }
}

For review: Just noting... we no longer need to manually propagate the async context to EnqueueMicrotask() since v8 finally closed that gap recently. Just hadn't gotten around to removing this previously.

argv.addAll(args);
// argv.addAll(args.begin(), args.end());

Unfortunately I don't think that works. args here does not have a begin() or end() as far as I'm aware.
