Unify how missing field entries are handle in knn formats (#13641) 
During segment merge we must verify that a given field has vectors and exists. The typical knn format checks assume the per-field format is used and thus only check for `null`. 

But we should check for field existence in the field info and verify it has dense vectors

Additionally, this commit unifies how the knn formats work and they will throw if a non-existing field is queried. Except for PerField format, which will return null (like the other per field formats)

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.
