LUCENE-10480: (Backporting) Use BulkScorer to limit BMMScorer to only top-level
disjunctions (#1037)
> Specialize 2-clauses disjunctions

> WANDScorer is nice, but it also has lots of overhead to maintain its
> invariants: one linked list for the current candidates, one priority queue of
> scorers that are behind, another one for scorers that are ahead. All this
> could be simplified in the 2-clauses case, which feels worth specializing for
> as it's very common that end users enter queries that only have two terms?
