perf jevents: Add metric DefaultShowEvents

Browse Source 
Some Default group metrics require their events showing for
consistency with perf's previous behavior. Add a flag to indicate when
this is the case and use it in stat-display.

As events are coming from Default metrics remove that default hardware
and software events from perf stat.

Following this change the default perf stat output on an alderlake looks like:
```
$ perf stat -a -- sleep 1

 Performance counter stats for 'system wide':
