LUCENE-6260: Simplify ExactPhraseScorer.

> ExactPhraseScorer tries to intersect positions using windows of 4096
> documents. In LUCENE-2410 it was reported that it helped a lot but I tried
> again on wikibig with a simpler impl that does advance one position at a time
> and the performance difference was only of a few percents. I'm guessing that
> maybe other changes (eg. the new postings format?) do not make this behaviour
> as useful as it used to be?
