perf session: Pass evsel in event_ops->sample()
Resolving the sample->id to an evsel since the most advanced tools, report and annotate, and the others will too when they evolve to properly support multi-event perf.data files. Good also because it does an extra validation, checking that the ID is valid when present. When that is not the case, the overhead is just a branch + function call (perf_evlist__id2evsel).
