perf list: Support printing MetricExpr with --debug
Output the metric expr in perf list when --debug is specified, so that the user can check the formula. Before: % perf list ... unc_m_power_channel_ppd [Cycles where DRAM ranks are in power down (CKE) mode. Derived from unc_m_power_channel_ppd. Unit: uncore_imc] uncore_imc_2/event=0x85/ After: % perf list --debug ... unc_m_power_channel_ppd [Cycles where DRAM ranks are in power down (CKE) mode. Derived from unc_m_power_channel_ppd. Unit: uncore_imc] Perf: uncore_imc_2/event=0x85/ MetricExpr: (unc_m_power_channel_ppd / unc_m_clockticks) * 100.
