Simplify task executor for concurrent operations (#12499) 
This commit removes the QueueSizeBasedExecutor (package private) in favour of simply offloading concurrent execution to the provided executor. In need of specific behaviour, it can all be included in the executor itself.

This removes an instanceof check that determines which type of executor wrapper is used, which means that some tasks may be executed on the caller thread depending on queue size, whenever a rejection happens, or always for the last slice. This behaviour is not configurable in any way, and is too rigid. Rather than making this pluggable, I propose to make Lucene less opinionated about concurrent tasks execution and require that users include their own execution strategy directly in the executor that they provide to the index searcher.

Relates to #12498

Building

Basic steps:

  1. Install OpenJDK 17 or 18.
  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.
