Update WebSocket blocked ports to match the Fetch spec
Adresses #9949.
This adds a function that tests whether a request should be blocked or not based on it's url's scheme and port. It also adds testing for port restriction to the `main_fetch` method. More info in eb07418c83.
@Ms2ger In https://github.com/whatwg/html/issues/841, @annevk proposes to remove port restrictions from websockets. Should we go ahead do that, given that the spec hasn't been changed yet?

test websocket origin set in worker
Fixes#9535
This crashes and I'm not sure how to debug it (and whether it's a problem with the browser or more likely a problem with the test):
```
./mach test-wpt /websockets/opening-handshake/003-sets-origin.worker --log-raw wpt.log Running 1 tests in web-platform-tests
▶ CRASH [expected OK] /websockets/opening-handshake/003-sets-origin.worker
Ran 1 tests finished in 2.0 seconds.
• 0 ran as expected. 0 tests skipped.
• 1 tests crashed unexpectedly
```
Also, should the test file be in `/websockets/` or `/websockets/opening-handshake/`?

Fix the Node.replaceChild tests
That method first does "if node is a host-including inclusive ancestor of parent,
throw a HierarchyRequestError" and only then "if child’s parent is not parent,
throw a NotFoundError exception".

Fix the "get the parent" loop when dispatching event (fixes#6733)
The DOM specification says:
> A document's get the parent algorithm, given an event, returns null
> if event's type attribute value is "load" or document does not have
> a browsing context, and the document's associated Window object
> otherwise.
