Source/WebCore:
Drop legacy MainThreadTaskQueue & EventLoopTaskQueue classes. Code that was using MainThreadTaskQueue
is now calling callOnMainThread() directly. Call that was using EventLoopTaskQueue is now using the
HTML event loop directly. If said code needed to cancel tasks or check if a previously scheduled task
is still pending, it now relies on WTF::CancellableTask / WTF::TaskCancellationGroup to do so.

Source/WTF:
We recently introduced the WTF::CancellableTask in order to be able to cancel
a pending task in the event loop, and/or check if the task is still pending.
It worked great as a replacement for EventLoopDeferrableTask. However, it was
insufficient as a replacement for task queues (such as MainThreadTaskQueue &
EventLoopTaskQueue) since there was no convenient way to cancel a group of
tasks. To address this, I am introducing WTF::TaskCancellationGroup. Whenever one
needs to create a CancellableTask, it now needs to provide a TaskCancellationGroup.
Several CancellableTask objects can share the same TaskCancellationGroup. Code now
now schedule one or more CancellableTasks on the event loop and hold on
to a TaskCancellationGroup. If they need to cancel those tasks, they can simply
call cancel() on the TaskCancellationGroup. They can also check if previously
scheduled tasks are still pending via TaskCancellationGroup::hasPendingTask().
