perf x86/topdown: Complete topdown slots/metrics events check

It's not complete to check whether an event is a topdown slots or
topdown metrics event by only comparing the event name since user
may assign the event by RAW format, e.g.

perf stat -e '{instructions,cpu/r400/,cpu/r8300/}' sleep 1

 Performance counter stats for 'sleep 1':

     <not counted>      instructions
     <not counted>      cpu/r400/
   <not supported>      cpu/r8300/

       1.002917796 seconds time elapsed

       0.002955000 seconds user
       0.000000000 seconds sys

The RAW format slots and topdown-be-bound events are not recognized and
not regroup the events, and eventually cause error.

Thus add two helpers arch_is_topdown_slots()/arch_is_topdown_metrics()
to detect whether an event is topdown slots/metrics event by comparing
the event config directly, and use these two helpers to replace the
original event name comparisons.
