LUCENE-10110: MultiCollector should conditionally wrap single leaf collector
(#303)
MultiCollector should wrap single leaf collector that wants to skip low-scoring
hits
but the combined score mode doesn't allow it.

> MultiCollector adapts the score mode of multiple collectors so that they can
> run together in a search. If a collector wants to skip low-scoring hits, this
> adapter ensures that the other collectors still see all hits. Although, when
> all these collectors have early terminated, we allow the skipping collector
> to start propagating the minimum score. This is not valid because the weight
> of the query is built from the combined score mode of all collectors at the
> beginning of the search.
> So we should always ignore the minimum score in MultiCollector if the
> combined score mode is different than TOP_SCORES.
