Adrien Grand 1807f86751 Generalize how queries on `_index` are handled at rewrite time (#52815) ... Generalize how queries on `_index` are handled at rewrite time (#52486) Since this change refactors rewrites, I also took it as an opportunity to adrress #49254: instead of returning the same queries you would get on a keyword field when a field is unmapped, queries get rewritten to a MatchNoDocsQueryBuilder. This change exposed a couple bugs, like the fact that the percolator doesn't rewrite queries at query time, or that the significant_terms aggregation doesn't rewrite its inner filter, which I fixed.
