Subject: [PATCH v2 07/11] perf c2c: Refactor node display macro

The macro DISPLAY_HITM() is used to calculate HITM percentage introduced
by every node and it's shown for the node info.

This patch refactors the macro, it is renamed it as DISPLAY_METRICS().
And the parameters is changed for passing the metric's statistic value
and the sum value, this is flexsible for later's extension, e.g. it's
easier to be used for metrics which combines multiple fields from
structure c2c_stats.
