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
