This PR adds `CloseEvent` as a global, which can be disabled
via the --no-experimental-websocket flag.
```js
const ws = new WebSocket('...')
ws.addEventListener('close', (event) => {
assert(event instanceof CloseEvent)
})
```

This is the initial work to bootstrap Web interfaces that are defined
with extended attributes `[Exposed=*]`.
The ShadowRealm instances are garbage-collected once it is
unreachable. However, V8 can not infer the reference cycles between
the per-realm strong persistent function handles and the realm's
context handle. To allow the context to be gc-ed once it is not
reachable, the per-realm persistent handles are attached to the
context's global object and the persistent handles are set as weak.
