libperf: Add perf_cpu_map struct
Add perf_cpu_map struct to libperf.
It's added as a declaration into:
include/perf/cpumap.h
which will be included by users.
The perf_cpu_map struct definition is added into:
include/internal/cpumap.h
which is not to be included by users, but shared within perf and
libperf.
We tried the total separation of the perf_cpu_map struct in libperf, but
it lead to complications and much bigger changes in perf code, so we
decided to share the declaration.
