Jim Ferenczi f05af0a382 Enable index-time sorting (#24055)
This change adds an index setting to define how the documents should be sorted inside each Segment.
It allows any numeric, date, boolean or keyword field inside a mapping to be used to sort the index on disk.
It is not allowed to use a `nested` fields inside an index that defines an index sorting since `nested` fields relies on the original sort of the index.
This change does not add early termination capabilities in the search layer. This will be added in a follow up.
