  Generate two sets of additional metrics for Arm64, where the topdown
set decomposes yet further. The metrcs primarily use json events,
where the json contains architecture standard events. Not all events
are in the json, such as for a53 where the events are in
sysfs. Workaround this by adding the sysfs events to the metrics but
longer-term such events should be added to the json.

The patches should be applied on top of:
https://lore.kernel.org/lkml/20240228175617.4049201-1-irogers@google.com/

v2. The cycles metrics are now made common and shared with AMD and
    Intel, suggested by Kan Liang <kan.liang@linux.intel.com>. This
    assumes these patches come after the AMD and Intel sets.
