async_hooks: ensure AsyncLocalStore instances work isolated 
Avoid that one AsyncLocalStore instance changes the state of another
AsyncLocalStore instance by restoring only the owned store instead
the complete AsyncContextFrame.

James M Snell a369818b1e lib: add defaultValue and name options to AsyncLocalStorage 
The upcoming `AsyncContext` specification adds a default value and name
to async storage variables. This adds the same to `AsyncLocalStorage`
to promote closer alignment with the pending spec.

```js
const als = new AsyncLocalStorage({
  name: 'foo',
  defaultValue: 123,
});

console.log(als.name);  // 'foo'
console.log(als.getStore());  // 123
```
