LUCENE-9935: Enable bulk merge for stored fields with index sort (#134)
This commit enables bulk-merges (i.e., raw chunk copying) for stored
fields when index sort is enabled
> Bulk merges for stored fields when index sorting is enabled

> Today stored fields disable bulk merges entirely when index sorting is
> enabled. However when sorting by low-cardinality fields or when the index
> sort is correlated with the order in which documents get indexed, we could
> likely still have efficient bulk merges.
> For instance, if you are merging two segments that are sorted on a field that
> can only take 2 values, one could bulk merge the first half of the first
> segment, then the first half of the second segment, then the second half of
> the first segment, and finally the second half of the second segment.
