chore: port tests over

This port isn't the best. Vite builds are ran multiple times with different modules configuration. The ideal abstraction is to have unit tests instead and Vite should "trust" that it works, but this will do for now.

I also skipped lightningcss tests for now. Check css-modules-lightningcss.spec.ts for notes.
