LUCENE-9523: Speed up query shapes for geometries that generate multiple points
(#1866)
In query shapes over shape fields, skip points while traversing the BKD tree
when the relationship with the document is already known

> When indexing lines or polygons into a shape field, we generally index
> multiple points for the same document. When querying, we typically visited a
> subset of this points. In many cases when visiting points from the same
> document, we already know the relationship and therefore computing the
> relationship between that point and the query shape is not necessary.
> When using dense visitors(eg. visitors backed by a FixedBitSet), we can check
> if the relationship is already known and therefore skip that point.
> Finally for intersects relationship we normally use sparse visitors but I
> wonder in the case where the number of points >> number of docs, we should
> use a dense visitor so we can skip points from documents where we know it
> intersects.
