perf top: Add --all-cgroups option

The --all-cgroups option is to enable cgroup profiling support.  It
tells kernel to record CGROUP events in the ring buffer so that 'perf
top' can identify task/cgroup association later.

Committer testing:

Use:

  # perf top --all-cgroups -s cgroup_id,cgroup,pid
