perf evlist: Introduce evlist__for_each() & friends
For the common evsel list traversal, so that it becomes more compact.
Use the opportunity to start ditching the 'perf_' from 'perf_evlist__',
as discussed, as the whole conversion touches a lot of places, lets do
it piecemeal when we have the chance due to other work, like in this
case.
