perf cpumap: Tidy libperf includes

Use public API when possible, don't include internal API in header
files in evsel.h. Fix any related breakages.

Committer note:

There was one missing case, when building for arm64:

  arch/arm64/util/pmu.c: In function 'pmu_events_table__find':
  arch/arm64/util/pmu.c:18:30: error: invalid use of undefined type 'struct perf_cpu_map'
     18 |                 if (pmu->cpus->nr != cpu__max_cpu().cpu)
        |                              ^~

Fix it by adding one more exception, including <internal/cpumap.h>
