perf tool: Add hpp interface to enable/disable hpp column
Adding perf_hpp__column_enable function to enable/disable hists column and removing diff command specific stuff 'need_pair and show_displacement' from hpp code. The diff command now enables/disables columns separately according to the user arguments. This will be helpful in future patches where more columns are added into diff output.
