### Description
While we have added bulk scoring, which can provide a substantial
performance boost, we still don't use it everywhere. I happened to notice its
missing from filter search & higher level searches (fixed for 10.4), but there
are some others.
Looking at the code, there are various places where I still see
`RandomVectorScorer.score` that might benefit from the bulk scorer API.
- [ ] HnswGraphBuilder#diversityCheck (I am looking at this one now)
- [ ] NeighborArray#isWorstNonDiverse
Now, there are also places that use `VectorScorer.score()` that could
benefit from bulk scoring
- [ ] DiversifyingChildrenVectorScorer#nextParent (bulk score the children?)
- [ ] VectorSimilarityScorerSupplier should maybe satisfy the BulkScorer
interface and delegate correctly?
- [ ] FullPrecisionFloatVectorSimilarityValuesSource satisfies the
DoubleValues interface, which...doesn't have any bulk interfaces :(. But might
benefit from them.
- [ ] Same for `VectorSimilarityValuesSource`
