perf evsel: Support printing callchains with arrows
The EVSEL__PRINT_CALLCHAIN_ARROW options can be used to print callchains
with arrows for readability. It will be used 'sched timehist' command
like below:
__schedule <- schedule <- schedule_timeout <- rcu_gp_kthread <- kthread <- ret_from_fork
__schedule <- schedule <- schedule_timeout <- rcu_gp_kthread <- kthread <- ret_from_fork
__schedule <- schedule <- worker_thread <- kthread <- ret_from_fork
