…nvoyproxy#14799) Fix a potential use-after-free error in ScaledRangeTimerManagerImpl by adding a processing_timers_ flag to the timer queues that is set during onQueueTimerFired processing. This flag is checked when a timer is removed to ensure that the timer's queue isn't deleted while it is in a callback triggered by onQueueTimerFired.
