perf hists browser: Count number of hierarchy entries
Add nr_hierarchy_entries field to keep current number of (unfolded) hist
entries. And the hist_entry->nr_rows carries number of direct children.
But in the hierarchy mode, entry can have grand children and callchains.
So update the number properly using hierarchy_count_rows() when toggling
the folded state (by pressing ENTER key).
