LUCENE-10480: Use BMM scorer for 2 clauses disjunction (#972) (#1002)

> 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?
