add bulk intoBitSet for SortedDocValues ordinal ranges

[iprithv]

extends the unified two-phase strategy from #16177 to SortedDocValues. Ordinal range queries now bulk-evaluate through intoBitSet instead of confirming matches() one doc at a time.

I wonder if this is the right tradeoff for ANN-backed indices in general. Losing the ANN structure for the whole segment after a small vector update and falling back to exact search until merge feels fairly expensive and potentially surprising.

Maybe this only really makes sense for flat indices where there is no ANN structure to invalidate?

The use case that feels more important to me is actually the opposite one: updating other fields/doc values without having to rewrite vectors or rebuild the ANN structure.

I saw the “change of model” use case mentioned in the PR, but in that situation you typically need to reindex everything anyway, so I’m not sure this optimization helps much there.

Wrong PR, sorry for the noise
