### Description This change add the ability to do prefetch during Approximate search and exact search. The changes include: 1. New prefetch interface on KNNVectorValues and RandomVectorScorer. 2. Integrate Prefetch during graph search. 3. Integrate prefetch when code fallback to exact search. 4. Only prefetch if numOfOrds > 1 ### Next Steps 1. Run benchmarks to show the improvements 2. Before doing prefetch compact the closer vector ids to ensure that prefetch is not happening for every docId. <!-- If this is your first contribution to Lucene, please make sure you have reviewed the contribution guide. https://github.com/apache/lucene/blob/main/CONTRIBUTING.md --> -- This is an automated message from the Apache Git Service.
