*Lay foundation to batch packets efficiently for graphs *Dynamically copy packets with max threshold set with DEBUG_HIP_GRAPH_BATCH_SIZE, if not stagger packet copy with pow2 *Default threshold for DEBUG_HIP_GRAPH_BATCH_SIZE is 256 *If TS are not collected for a signal for reuse, create a new signal. This can potentially increase signal footprint if the handler doesn't run fast enough.
