So as I mentioned earlier, Chromium has a way to track what scheduled some async tasks (seems to be used for devtools and for ad tracking), so I made a patch that prints out the type of event, and for async sources some string related to the scheduler, for each event dispatch

maybe there's a way to turn that into telemetry that we could get, but the timeline on getting that will be months

I also don't expect that this async task tracking covers every event with an async source, so we might not get a full list of such events

but I might run a number of Blink web tests overnight and see what results we get
