perf hists: Use own hpp_list for hierarchy mode

Browse Source 
Now each hists has its own hpp lists in hierarchy.  So instead of having
a pointer to a single perf_hpp_fmt in a hist entry, make it point the
hpp_list for its level.  This will be used to support multiple sort keys
in a single hierarchy level.
