perf parse-events: Remove "not supported" hybrid cache events

By default, we create two hybrid cache events, one is for cpu_core, and
another is for cpu_atom. But Some hybrid hardware cache events are only
available on one CPU PMU. For example, the 'L1-dcache-load-misses' is only
available on cpu_core, while the 'L1-icache-loads' is only available on
cpu_atom. We need to remove "not supported" hybrid cache events. By
extending is_event_supported() to global API and using it to check if the
hybrid cache events are supported before being created, we can remove the
"not supported" hybrid cache events.

Before:

 # ./perf stat -e L1-dcache-load-misses,L1-icache-loads -a sleep 1

 Performance counter stats for 'system wide':

            52,570      cpu_core/L1-dcache-load-misses/
   <not supported>      cpu_atom/L1-dcache-load-misses/
   <not supported>      cpu_core/L1-icache-loads/
         1,471,817      cpu_atom/L1-icache-loads/

       1.004915229 seconds time elapsed

After:

 # ./perf stat -e L1-dcache-load-misses,L1-icache-loads -a sleep 1

 Performance counter stats for 'system wide':

            54,510      cpu_core/L1-dcache-load-misses/
         1,441,286      cpu_atom/L1-icache-loads/
