perf tools: Add perf_event__synthesize_id_sample()
Add perf_event__synthesize_id_sample() to enable the synthesis of
ID samples.
This is needed by perf inject. When injecting events from a guest perf.data
file, there is a possibility that the sample ID numbers conflict. In that
case, perf_event__synthesize_id_sample() can be used to re-write the ID
sample.
