perf list: Extend raw-dump to certain kind of events

Extend 'perf list --raw-dump' to 'perf list --raw-dump [hw|sw|cache
|tracepoint|pmu|event_glob]' in order to show the raw-dump of a certain
kind of events rather than all of the events.

Example:

Before this patch:

 $ perf list --raw-dump hw
 branch-instructions branch-misses bus-cycles cache-misses
 cache-references cpu-cycles instructions stalled-cycles-backend
 stalled-cycles-frontend
 alignment-faults context-switches cpu-clock cpu-migrations
 emulation-faults major-faults minor-faults page-faults task-clock
 ...
 ...
 writeback:writeback_thread_start writeback:writeback_thread_stop
 writeback:writeback_wait_iff_congested
 writeback:writeback_wake_background writeback:writeback_wake_thread

As shown above, all of the events are printed.

After this patch:

 $ perf list --raw-dump hw
 branch-instructions branch-misses bus-cycles cache-misses
 cache-references cpu-cycles instructions stalled-cycles-backend
 stalled-cycles-frontend

As shown above, only the hw events are printed.
