perf stat report: Process event update events

Adding processing of event update events, so perf stat report can store
additional info for events - unit,scale,name.

Committer note:

Before:

# perf stat record -e power/energy-cores/ -a
^C
Performance counter stats for 'system wide':

77.41 Joules power/energy-cores/

1.597176695 seconds time elapsed

# perf stat report

Performance counter stats for '/home/acme/bin/perf stat record -e power/energy-cores/ -a':

332,488,114,176 power/energy-cores/

1.597176695 seconds time elapsed

#

After, using the same perf.data file generated in the "Before" case
above:

# perf stat report

Performance counter stats for '/home/acme/bin/perf stat record -e power/energy-cores/ -a':

77.41 Joules power/energy-cores/

1.597176695 seconds time elapsed
