This improves testing of mismatched field numbers by - improving `AssertingDocValuesProducer` to detect mismatched field numbers, - introducing a `MismatchedCodecReader` to actually test mismatched field numbers on `DocValuesProducer` (a `MismatchedLeafReader` wrapping a `SlowCodecReaderWrapper` doesn't work since `SlowCodecReaderWrapper` implicitly resolves the correct `FieldInfo` object), - introducing an explicit test for mismatched field numbers for doc values, points, postings and knn vectors. These new tests uncovered a bug when merging sorted doc values, which would call the underlying doc values producer with the merged field info. Closes #13805

Building
Basic steps:
- Install OpenJDK 21.
- Clone Lucene's git repository (or download the source distribution).
- 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.
