perf jevents: Add new structure to pass json fields.

Browse source

This patch adds new structure called 'json_event' inside jevents.c
file to improve the callback prototype inside jevent files.

Initially, whenever user want to add new field, they need to update
in all function callback which make it more and more complex with
increased number of parmeters.

With this change, we just need to add it in new structure 'json_event'.
