Add a simple tool, poller_perf, to evaluate cost to run non-timed
poller or timed poller by any period, number of pollers.
struct spdk_thread and struct spdk_thread_stats can have the count
of poller runs but we do not have any particular use case for it.
So the poller_perf tool use its global counter for now.
By following similar tools, event_perf and reactor_perf, run
poller_perf once for non-timed poller and once for timed poller.
