perf list: Move extra details printing to new option
Move the printing of perf expressions and internal events to a new clearer --details flag, instead of lumping it together with other debug options in --debug. This makes it clearer to use. Before perf list --debug ... unc_m_power_critical_throttle_cycles [Cycles all ranks are in critical thermal throttle. Unit: uncore_imc] uncore_imc_2/event=0x86/ MetricName: power_critical_throttle_cycles % MetricExpr: (unc_m_power_critical_throttle_cycles / unc_m_clockticks) * 100. after perf list --details ... unc_m_power_critical_throttle_cycles [Cycles all ranks are in critical thermal throttle. Unit: uncore_imc] uncore_imc_2/event=0x86/ MetricName: power_critical_throttle_cycles % MetricExpr: (unc_m_power_critical_throttle_cycles / unc_m_clockticks) * 100.
