This wraps happy eyeballs in two places, the place where we make the
JSON request to Chromium and the actual CDP WebSocket request.
It required changes inside our happy eyeballs implementation since the
[websocket library does not
set](https://github.com/websockets/ws/blob/master/lib/websocket.js#L714)
the `clientRequestOptions.hostname` field, it just sets the `host` field
where we then fall back to when its not set.
This test would pass before Node.js 18 and fail after Node.js 18 without
my changes.
Fixes https://github.com/microsoft/playwright/issues/20364
Fixes#15474.
Notes:
* page-level requests that are also handled by a SW's fetch handler, should not be interceptable at the page-level
* `Network.requestWillBeSent` does not provide enough metadata for Playwright to fire the `request` event at that time, so it does it as soon as it gets to the end of the request lifecycle
The Service Worker tests had some races in them that only were apparent
on the bots. To repro, I ran the tests with:
```
xvfb-run taskset -c 0 npm run ctest -- chromium.spec.ts --headed --reporter=line --repeat-each 10 --workers=1
```
Just because Playwright has a SW, does not mean the worker has fully loaded
it's main/import scripts.
