perf tools: Enable config and setting names for legacy cache events

This patch allows setting config terms for legacy cache events.
For example:

  # perf stat -e L1-icache-misses/name=valA/ -e branches/name=valB/ ls
  ...
   Performance counter stats for 'ls':

              11299      valA
             451605      valB

        0.000779091 seconds time elapsed

  # perf record -e cache-misses/name=inh/ -e cache-misses/name=noinh,no-inherit/ bash
  # ls
  # exit
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.023 MB perf.data (131 samples) ]
  # perf report --stdio | grep -B 1 'Event count'
  # Samples: 105  of event 'inh'
  # Event count (approx.): 109118
  --
  # Samples: 26  of event 'noinh'
  # Event count (approx.): 48302

A test case is introduced to test this feature.
