perf hists: Add perf_hpp_list register helpers

Adding 2 perf_hpp_list register helpers:

  perf_hpp_list__column_register()
  perf_hpp_list__register_sort_field()

to be called within existing helpers:

  perf_hpp__column_register()
  perf_hpp__register_sort_field()

to register format entries within global perf_hpp_list object.
