Add 'profile' support for knn query on HNSW with early termination

[tteofili]

This is a followup to #127223 that leverages some changes in Lucene 10.3 to extend and reuse HnswQueueSaturationCollector to simplify code in ES for early termination on HNSW.
Very importantly, it also adds 'profile' support so that vector_ops are now correctly recorded also when early termination is enabled.

Hi @tteofili, I've created a changelog YAML for you.

Do you think this can work with ESDiversifyingChildren*KnnVectorQuery objects as well? I would expect it to work OK as we still delegate to the underlying collector.

Or did you test it and it not provide good results?

yes, it works also with diversifying knn query (had run benchmarks in the original PR too), I've fixed this in 53cfeb5.
