Add mult-leaf optimizations for diversify children collector (#13121) 
This adds multi-leaf optimizations for diversified children collector. This means as children vectors are collected within a block join, we can share information between leaves to speed up vector search.

To make this happen, I refactored the multi-leaf collector slightly. Now, instead of inheriting from TopKnnCollector, we inject a inner collector.

Online Documentation

This README file only contains basic setup instructions. For more comprehensive documentation, visit:

Building

Basic steps:

  1. Install OpenJDK 21.
  2. Clone Lucene's git repository (or download the source distribution).
  3. Run gradle launcher script (gradlew).

We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.

See Contributing Guide for details.
