perf stat: Do not allow --for-each-cgroup without cpu
The cgroup mode should work with cpu events. Warn if --for-each-cgroup
option is used with a task target like existing -G option.
# perf stat --for-each-cgroup . sleep 1
both cgroup and no-aggregation modes only available in system-wide mode
Usage: perf stat [<options>] [<command>]
-G, --cgroup <name> monitor event in cgroup name only
-A, --no-aggr disable CPU count aggregation
-a, --all-cpus system-wide collection from all CPUs
--for-each-cgroup <name>
expand events for each cgroup
