Move legacy tests from OSS to fbandroid/java/com/facebook/fbreact (#41802)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/41802

Those tests are not executing at all, they're just compiled.
Our internal infra is still depending on some bits of it though, so I'm moving them to `fbandroid/java/com/facebook/fbreact
