--When mQueueLength >= mQueueSize happens in CHIPCircularTLVBuffer::GetNewBuffer, if mProcessEvictedElement is set with AlwaysFail, EvictHead would fail when logging Event. We should let EvictHead and Init succeed, then later EnsureSpaceInCircularBuffer would help get enough space for new event in LogEventPrivate. add event overflow testing
