perf stat: Add id into perf_stat struct

Browse source 
We need fast way to identify evsel as transaction event for shadow
counters computation. Currently we are using possition (in evlist) based
way.

Adding 'id' into 'struct perf_stat' so it can carry transaction event ID
and we can use it for shadow counters computations.
