[w3ctag/design-reviews] Extended lifetime shared workers (Issue #1089)

domenic created an issue (w3ctag/design-reviews#1089)

こんにちは TAG-さん!

I'm requesting an early TAG design review of extended lifetime shared workers.

We propose adding a new option to the `SharedWorker` constructor that serves as a request to extend its lifetime after all current clients have unloaded:

```js
const sharedWorker = new SharedWorker(url, { extendedLifetime: true });
```

The primary use case here is to allow pages to perform some async work that requires JavaScript after a page unloads, without needing to rely on a service worker.
