LUCENE-7716: Reduce specialization in TopFieldCollector.

> TopFieldCollector optimizes the single-comparator case. I think we could
> replace this specialization with a MultiLeafFieldComparator wrapper,
> similarly to how MultiCollector works. This would have the benefit of
> replacing code duplication of non-trivial logic with a simple wrapper that
> delegates calls to its sub comparators.
