Ensure to use IOContext.READONCE when reading segment files (#13574) 
This commit uses IOContext.READONCE in more places where the index input is clearly being read once by the thread opening it. We can then enforce that segment files are only opened with READONCE, in the test specific Mock directory wrapper.

Much of the changes in this PR update individual test usage, but there is one non-test change to Directory::copyFrom.

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.
