This commit removes the global caching of the field query and replaces it with a caching per field. Each field can use a different `highlight_query` and the rewriting of some queries (prefix, automaton, ...) depends on the targeted field so the query used for highlighting must be unique per field. There might be a small performance penalty when highlighting multiple fields since the query needs to be rewritten once per highlighted field with this change. Fixes elastic#25171
