lib: make AbortSignal cloneable/transferable

Allows for using `AbortSignal` across worker threads and contexts.

```js
const ac = new AbortController();
const mc = new MessageChannel();
mc.port1.onmessage = ({ data }) => {
  data.addEventListener('abort', () => {
    console.log('aborted!');
  });
};
mc.port2.postMessage(ac.signal, [ac.signal]);
```
