Make three small changes for the support. First, update damos_filter_for_ops() to treat probe_hits_wsum filter as core filter. Second, Update destination damos_filter->range_{min,max} for probe_hits_wsum type damos filter commits. Third, extend damos_filter_match() to handle probe_hits_wsum type filter. Calculate the weighted sum of the given region and compare it with the given filter's target weighted sum range.
