TabGroup never really made any difference in which thread something go dispatched to. This was the intended use, but development of TabGroups with abstract main threads never made it that far. The good thing is that thish makes it safe to also remove to the SystemGroup and instead switch all SystemGroup dispatches to dispatches to main thread. Timers for setTimeout and workers were the sole users of wrapped and throttled event targets, that those throttled queues have been moved to the BrowsingContextGroup and are now accessed explicitly. The SchedulerEventTarget has been removed, since there are no longer a separate event target for every TaskCategory. Instead a LabellingEventTarget has been added to DocGroup to handle the case where an event is dispatched do DocGroup or when an AbstractThread is created using a DocGroup. This means that we'll actually label more events correctly with the DocGroup that they belong to. DocGroups have also been moved to BrowsingContextGroup.
