Use BulkSimScorer on MultiNormsLeafSimScorer

[HUSTERGS]

Description

This is a follow up of the comment from #15039 that trying to use the newly intruduced BulkSimScorer on MultiNormsLeafSimScorer. Actually this change didn't bring any speedup, at least on my machine, maybe it's already auto-vectorized, but since it didn't bring any slowdown either and it does simplify the code, I think this change might be acceptable.
