Similar to #82409, but for date fields.

Allows searching on date field types (date, date_nanos) when those fields are not indexed (index: false) but just doc values are enabled.

This enables searches on archive data, which has access to doc values but not index structures. When combined with searchable snapshots, it allows downloading only data for a given (doc value) field to quickly filter down to a select set of documents.

Relates #81210 and #52728
