Format codegen files

[kimdv]

Codegen was not formatted. IMO we should do that to keep the code consistent

This should be coordinated with some of the other PR's before merge

I deliberately decided not to format the generated files because it simplifies development: If you make changes to CodeGenerateion and re-generate the files, you aren’t hit with a wall of changes because now the files are no longer formatter.

If we want to format those files (which I think is a good idea), IMO the formatting should be done in CodeGeneration itself at generation time. That way running CodeGeneration will always generate formatted files. For this, CodeGeneration can depend on swift-format, similarly to how it depends on swift-syntax.

I don't format the generated files, but the code generation project 😅

Like template files etc.
Based on this comment:

Oh, I should have looked at the PR more closely, sorry. CodeGeneration itself should certainly be formatted by swift-format. Thanks for catching and fixing this. I wonder whether we can generalize this a little further to also include the examples (see inline comment).

[kimdv]

I tried to include all relevant files as you sugested.
With an if statement is exploded in cases, so I tought I did find all the files to exclude and then filter at the end

[ahoppen]

Thanks for catching that we didn’t format all of these files and fixing it.

[ahoppen]

This looks really nice 😍
