perf amd ibs: Decode Streaming-store flag in IBS OP raw dump

IBS OP on Zen6 and future platform can tag IBS samples that originate from
streaming-store instruction. When the PMU advertises this feature,
interpret IBS_OP_DATA2[8] bit as the streaming store indicator and show
it in the raw dump output.
