Resolve and safe constants cross-files

[LudvigHz]

Another one from me here 😅

When importing variables from other files, we need to keep the
declarations so the declarations are saved for future reference when
processing other files.

This fixes cases where declarations of variables passed to useTranslation are defined in other
files. The quirk here is that you need to ensure the files containing the declarations are parsed
before any other usages of those declarations.

maybe not that easy, but can you try to create a test for that?

Sure!
I added a test that should cover it now :)
