AOTClassLinking for the dynamic archive has been removed in [JDK-8367366](https://bugs.openjdk.org/browse/JDK-8367366). Currently, AOT-linked classes are supported for both the static archive and AOT cache. I've updated the comments to reflect that.

We probably should remove AOTClassLinking from static CDS archive as well. I've created [JDK-8368350](https://bugs.openjdk.org/browse/JDK-8368350) for that.
