For the sake of better documentation, add core_wide and target_cpu to
the tool.json. When the values of system_wide and
user_requested_cpu_list are unknown, use the values from the global
stat_config.
Example output showing how '-a' modifies the values in `perf stat`:
```
$ perf stat -e core_wide,target_cpu true
Performance counter stats for 'true':
0 core_wide
0 target_cpu
0.000993787 seconds time elapsed
0.001128000 seconds user
0.000000000 seconds sys
$ perf stat -e core_wide,target_cpu -a true
Performance counter stats for 'system wide':
1 core_wide
1 target_cpu
0.002271723 seconds time elapsed
$ perf list
...
tool:
core_wide
[1 if not SMT,if SMT are events being gathered on all SMT threads 1 otherwise 0. Unit: tool]
...
target_cpu
[1 if CPUs being analyzed,0 if threads/processes. Unit: tool]
...
```
