perf list: Output tool events
Add support in 'perf list' to output tool internal events, currently
only 'duration_time'.
Committer testing:
$ perf list dur*
List of pre-defined events (to be used in -e):
duration_time [Tool event]
Metric Groups:
$ perf list sw
List of pre-defined events (to be used in -e):
alignment-faults [Software event]
bpf-output [Software event]
context-switches OR cs [Software event]
cpu-clock [Software event]
cpu-migrations OR migrations [Software event]
dummy [Software event]
emulation-faults [Software event]
major-faults [Software event]
minor-faults [Software event]
page-faults OR faults [Software event]
task-clock [Software event]
duration_time [Tool event]
$ perf list | grep duration
