In x86, hardware uses CLOSID and an RMID to identify a control group and
a monitoring group respectively. When a user creates a control or monitor
group these details are not visible to the user. These details can help
debugging.

Add CLOSID(ctrl_hw_id) and RMID(mon_hw_id) to the control/monitor groups
display in resctrl interface. Users can see these details when resctrl
is mounted with "-o debug" option.

Other architectures do not use "CLOSID" and "RMID". Use the names
ctrl_hw_id and mon_hw_id to refer to "CLOSID" and "RMID" respectively in
an effort to keep the naming generic.

For example:
  $cat /sys/fs/resctrl/ctrl_grp1/ctrl_hw_id
  1
  $cat /sys/fs/resctrl/mon_groups/mon_grp1/mon_hw_id
  3
