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
