Can we separate "top scorer" from "sub scorer"?

    Description

      This is just an exploratory patch ... still many nocommits, but I
      think it may be promising.

      I find the two booleans we pass to Weight.scorer confusing, because
      they really only apply to whoever will call score(Collector) (just
      IndexSearcher and BooleanScorer).

      The params are pointless for the vast majority of scorers, because
      very, very few query scorers really need to change how top-scoring is
      done, and those scorers can only score top-level (throw throw UOE
      from nextDoc/advance). It seems like these two types of scorers
      should be separately typed.
