perf cpumap: Give CPUs their own type
A common problem is confusing CPU map indices with the CPU, by wrapping
the CPU with a struct then this is avoided. This approach is similar to
atomic_t.
Committer notes:
To make it build with BUILD_BPF_SKEL=1 these files needed the
conversions to 'struct perf_cpu' usage:
tools/perf/util/bpf_counter.c
tools/perf/util/bpf_counter_cgroup.c
tools/perf/util/bpf_ftrace.c
Also perf_env__get_cpu() was removed back in "perf cpumap: Switch
cpu_map__build_map to cpu function".
Additionally these needed to be fixed for the ARM builds to complete:
tools/perf/arch/arm/util/cs-etm.c
tools/perf/arch/arm64/util/pmu.c
