Add converter for PatchSet protobuf messages

The use of ProtobufCodec requires that value classes need to be
annotated with @Column, which won't be possible as soon as we have
removed gwtorm. Hence, provide a hand-written converter for PatchSet
protobuf messages.

As protobuf PatchSets are currently used in caches and indices and we
don't want to invalidate those, we have to ensure binary compatibility.
Prove that the new converter generates binary compatible results via
dedicated tests. Those tests will be removed after this change.
