Compute the diff between two serializations of languages

[dslmeinte]

We can compute the diff between two serialization chunks of languages, but the diffs are given as generic diff. It'd be more useful if these differences were given in LionCore/M3-specific terms, such as NameChanged, etc. – more like language refactorings.

Apart from the predefined INamed, there is little information that can be used for this.

I mean specifically: serializations of languages, so of M2s, not any pair of serialization chunks.
