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.
