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.
