perf hists browser: Add support to display whole group data for raw columns 

Currently we don't display group members' values for raw columns like
'Samples' and 'Period' when in group report mode.

Uniting '__hpp__percent_fmt' and '__hpp__raw_fmt' function under new
function __hpp__fmt. It's basically '__hpp__percent_fmt' code with new
'fmt_percent' bool parameter added saying whether raw number or
percentage should be printed.

This way raw columns print out all the group members when
in group report mode, like:

  $ perf record -e '{cycles,cache-misses}' ls
  ...
  $ perf report --group --show-total-period --stdio
  ...
  #         Overhead                    Period  Command      Shared Object                             Symbol
