perf record: Add ID and to recorded event data when recording multiple events
Currently perf record does not write the ID or the to disk for
events. This doesn't allow report to tell if an event stream
contains one or more types of events. This patch adds this
entry to the list of data that record will write to disk if more
than one event was requested.
