Initially, every time we want to add new terms like chip, core thread etc,
we need to create corrsponding fields in pmu_events and event struct.
This patch adds an enum called 'aggr_mode_class' which store all these
aggregation like perpkg/percore. It also adds new field 'aggr_mode'
to capture these terms.
Now, if user wants to add any new term, they just need to add it in
the enum defined.
