PointInSetQuery does not terminate early if result iterator has no docs [LUCENE-9584]

Today, in a point in set query after BKD intersect we get a DocIdSetBuilder result, if result's iterator have no docs, then the PointInSetQuery still create ConstantScoreScorer with an empty DocIdSetIterator. 

In a Boolean Query, such as query = subQuery1 AND subQuery2 AND subQuery3 .... subQueryN

if subQuery1 is a PointInSetQuery and get an empty result iterator, and subsequent subQuery2 \~ subQueryN would still evaluate to call build scorer, this is an unnecessary cost for this query if subQuery1 have already got an empty result iterator .

Start with PointInSetQuery and trace the BKD intersect result through DocIdSetBuilder and ConstantScoreScorer. Verify the empty-iterator case and check that a Boolean query no longer builds subsequent scorers unnecessarily; the attached LUCENE-7.7.0-PointInSetQuery_terminate_early.patch is available for context.
