This breaks:

perf stat: Display event stats using aggr counts

Now aggr counts are ready for use. Convert the display routines to use
the aggr counts and update the shadow stat with them. It doesn't need
to aggregate counts or collect aliases anymore during the display. Get
rid of now unused struct perf_aggr_thread_value.

Note that there's a difference in the display order among the aggr mode.
For per-core/die/socket/node aggregation, it shows relevant events in
the same unit together, whereas global/thread/no aggregation it shows
the same events for different units together. So it still uses separate
codes to display them due to the ordering.

One more thing to note is that it breaks per-core event display for now.
The next patch will fix it to have identical output as of now.

Testing directly on it:

[acme@quaco perf]$ git checkout 8ecdc6436c19480ac9458ab94807aebc5c13de7f
Note: switching to '8ecdc6436c19480ac9458ab94807aebc5c13de7f'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

git switch -c <new-branch-name>

Or undo this operation with:

git switch -

Turn off this advice by setting config variable advice.detachedHead to false
