Dont post delayed DoWork for disabled queues. We could do this for
fences too but don't because that would break the throttling logic
which needs to know when the next delayed task is due to be run.

Contains a fix for the bug which previously was causing renderer hangs.

TaskQueue::GetNextScheduledWakeUp must return base::nullopt for
disabled queues because we no longer schedule wakeups for those. If we
don't do this then the TaskQueueThrottler will be fed misleading data
which causes it to misbehave.

Looks like there's still a bad interaction with the TaskQueueThrottler.
