Enable mock-maker-inline for Android JVM tests (#37646)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37646

I'm re-enabling a test that got disabled due to us not using mock-maker-inline in OSS. I'm also adding `mock-maker-inline` for OSS so it will be easier to convert tests to Kotlin as classes in Kotlin are final by default.

Changelog:
[Internal] [Changed] - Enable mock-maker-inline for Android JVM tests
