When a query of a filter gets rewritten to MatchNoDocsQuery, segments will not produce any results. We can therefore skip processing such segments. This applies to FilterByFilterAggregator and FiltersAggregator, as well as to TermsAggregator when it uses StringTermsAggregatorFromFilters internally; the latter is an adapter aggregator to FilterByFilterAggregator. Fixes elastic#94637
