SystemInformation and associated helpers StorageFileHelper, ApplicationDataStorageHelper and the OSVersion struct have not yet been ported. I have ported these in this PR, with support for multiple platforms (and Uno support(-ish)).

I'm not sure I see the point of these APIs. Perhaps SystemInformation on its own, but most of the other APIs seem to be just very low value wrappers over system APIs. @Arlodotexe we should consider whether it makes sense to bring back these APIs at all.

I agree, this needed proper evaluation as per #602.
