1877744 - Upstream wpt tests showing frequent crashes in mozilla::dom::WebSocketImpl::AssertIsOnTargetThread

In release builds, upstream wpt seems to be crashing a lot in websockets tests. This doesn't seem to happen when running the tests from mozilla-central, but does when running directly from a wpt checkout.

This seems to be why we have no recent stable build results in Interop 2023, because eventually we get into a state where we're unable to load the main test page, and so the job fails.

See https://community-tc.services.mozilla.com/tasks/FZV0RlUHR_CsaQBvRRqFpw/runs/0/logs/live/public/logs/live.log for an upstream log

Locally I reproduced this from a wpt checkout with a command like ./wpt run --no-restart-on-unexpected --log-tbpl - --channel=stable --binary ../gecko/obj-x86_64-pc-linux-gnu/dist/bin/firefox firefox websockets/ where the --binary points to a local build.

The stack looks like:

I can reproduce on macOS. It seems to be only worker tests that crash, for example /websockets/Close-1000-reason.any.worker.html?default

We added the release assertions in https://phabricator.services.mozilla.com/D186618 and also did a refactoring in bug 1868177
Kershaw, could you take a look?

This can be reproduced by running ./mach mochitest --disable-e10s dom/websocket/tests/test_websocket_sharedWorker.html.
I am surprised that WebSocketChannel::NotifyOnStart is supposed to be called on main thread, but WebSocketImpl::OnStart not.
