libperf: Document struct perf_cpu int16_t ABI limitation
struct perf_cpu.cpu is int16_t, limiting perf to 32767 CPUs. This is
part of the libperf ABI (returned by value from perf_cpu_map__cpu() and
friends), so widening it requires an ABI bump.
Add a comment on the struct definition noting this, and create a TODO
file to collect future ABI changes so they can be batched into a single
version bump.
