Description

This is a follow-up to recent changes that already started simplifying SimScorer, we can now:

• remove the notion of field from SimScorer (might help for LUCENE-8216)
• remove logic from LeafSimScorer to compute an upper bound of scores for entires segments, this should be done on top of impacts now.
