perf hists: Introduce output_resort_cb method
When dealing with nested hist entries it's helpful to have a way to
resort those nested objects.
Adding optional callback call into output_resort function and following
new interface function:
typedef int (*hists__resort_cb_t)(struct hist_entry *he);
void hists__output_resort_cb(struct hists *hists,
struct ui_progress *prog,
hists__resort_cb_t cb);
