JavaCallbackEmitter.emitJavaKeyClass(): Use directBufferAddress for compound types in equals and hashCode, i.e. use memory identitypulled

Use case is having a compound-type as userParam, which also acts as key, see MessageCallback13, Test4JavaCallback.chapter13().

The Java compound instance is re-created using the actual identical native memory (address),
which has been stored or passed in the native toolkit.
