perf c2c: Refactor display filter

perf c2c: Refactor display filter

When sorting on the respective metrics (lcl_hitm, rmt_hitm, tot_hitm),
the FILTER_HITM macro is used to filter out the cache line entries if
its overhead is less than 1%.

This patch introduces a static function filter_display() to replace that
macro and refines its parameters with a more flexible way, rather than
passing field name, it changes to pass the cache line's statistic and
sum value.
