feat: Add legacy simapp testing via build tags (#12121)

## Description This is a PoC just to know what the team thinks of it. Pros: - No need to re-write tests - We make sure that we are running all the same tests on both files Cons: - We need to run tests twice (although we would be running them twice if we copy&paste all of them) Closes: #12068 --- ### Author Checklist *All items are required.
