Subject: [PATCH v2 1/4] Add a new element for the struct perf_tool, and add the --per-event-dump option for perf script

This patch will add a new bool variable per_event_dump to mark the per-event-dump option,
and add the OPT_BOOLEAN for per-event-dump in the perf_data_file struct.

Changes since v1:
- remove the set for script.tool.per_event_dump variable,since the OPT_BOOLEAN
 will do the same thing.
