This commit deprecates the old access pattern used to create a KnowledgeIndex (`model.getKnowledge(X.class)`) in favor of using a new convention: `X.of(model)`. KnowledgeIndex implementations are now expected to provide a public static method named `of` that accepts a `Model` and returns an instance of the class. The instance should be created by calling `model.getKnowledge(Class<T>, Function<Model, T>)` which will ensure the index is cached in the given model. This change is the first step towards seeing if we can get full GraalVM native image support. It also makes using a KnowledgeIndex more ergonomic IMO, and remove reflection, which is generally a good thing. The deprecated method will eventually be removed in a subsequent release.
