perf hists: Add helper functions for hierarchy mode

The rb_hierarchy_{next,prev,last} functions are to traverse all hist
entries in a hierarchy.  They will be used by various function which
supports hierarchy output.

As the rb_hierarchy_next() is used to traverse the whole hierarchy, it
sometime needs to visit entries regardless of current folding state.  So
add enum hierarchy_move_dir and pass it to __rb_hierarchy_next() for
those cases.
