perf evlist: Add evlist__findnew_tracking_event() helper
Currently, intel-bts, intel-pt, and arm-spe may add tracking event to the
evlist. We may need to search for the tracking event for some settings.
Therefore, add evlist__findnew_tracking_event() helper.
If system_wide is true, evlist__findnew_tracking_event() set the cpu map
of the evsel to all online CPUs.
