LUCENE-10089 Disable numeric sort optim when needed (#286)
Add a method to SortField that allows to enable/ disable numeric
sort optimization with points, which is enabled by default from 9.0.
> Add a way to disable the sort optimizations to leverage points on numeric

> [~jimczi] [~romseygeek] [~mayya] and I were just looking at a case when it
> would be useful to be able to disable the sort optimization.
> Say you have a 8.x index that has a field that is indexed with IntPoint and
> NumericDocValuesField. This field is used for index sorting, and the
> SortField is created with SortField.Type.LONG.
> This was accepted in 8.x, but this is something that Lucene 9 would complain
> about: since the field is an integer, it should use SortField.Type.Int, not
> SortField.Type.LONG. If the field was not used for index sorting, then you
> could just switch to SortField.Type.INT and everything would work fine.
> However since the field is used for index sorting, if you switch to
> SortField.Type.INT, then index-time SortField objects are going to compare
> differently from search-time SortField objects, which in-turn will disable
> early termination of queries in TopFieldCollector.
> To be able to migrate from indices that fall in this scenario, it would be
> helpful to have an option that would disable the optimization to use points
> as well as the associated validation logic, similarly to what we do in 8.x to
> enable this optimization.
