perf tools: Factor out evsel__id_hdr_size()
Factor out evsel__id_hdr_size() so it can be reused.
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. To
re-write an ID sample, the old one needs to be removed first, which means
determining how big it is with evsel__id_hdr_size() and then subtracting
that from the event size.
