Add UUID to core SerializationContexts

Currently we only register a ProtoStream marshaller for java.util.UUID in the server as they are required for the event logger, however this will also be required by core for `MultiClusterEventCommand` and `ClusterEvent`. It's not possible to register a class in multiple contexts when utilising a TypeId, therefore in order to avoid having to provide a TypeId for UUIDs in both core and server, we should register this in the core's persistence initializers.
