perf c2c: Refactor display string

The display type is shown by combination the display string array and a
suffix string "HITMs", which is not friendly to extend display for other
sorting type (e.g. extension for peer operations).

This patch moves the suffix string "HITMs" into display string array for
HITM types, so it can allow us to not necessarily to output string
"HITMs" for new incoming display type.
