perf evsel: Add PERF_SAMPLE_READ sample related processing
For sample with sample type PERF_SAMPLE_READ the period value is stored
in the 'struct sample_read'.
Moreover if the read format has PERF_FORMAT_GROUP, the 'struct
sample_read' contains period values for all events in the group (for
which the sample's event is a leader).
We deliver separated samples for all the values contained within the
'struct sample_read'.
