libperf: Move 'idx' from tools/perf to perf_evsel::idx

Browse Source 
Move evsel::idx to perf_evsel::idx, so we can move the group interface
to libperf.

Committer notes:

Fixup evsel->idx usage in tools/perf/util/bpf_counter_cgroup.c, that
appeared in my tree in my local tree.

Also fixed up these:

$ find tools/perf/ -name "*.[ch]" | xargs grep 'evsel->idx'
tools/perf/ui/gtk/annotate.c:                      evsel->idx + i);
tools/perf/ui/gtk/annotate.c:                   evsel->idx);
$

That running 'make -C tools/perf build-test' caught.
