Initial Kotlin setup and migrate YogaConstants (#1829)

Summary:
X-link: https://github.com/facebook/react-native/pull/53133

# Changelog:
[Internal] -

As part of the ongoing effort to migrate the React Native codebase to Kotlin, this PR introduces the initial setup required for Kotlin support in Yoga.

- Added initial basic Kotlin configuration to the project.
- Migrated `YogaConstants` as an initial file to try out the first migration steps.

Pull Request resolved: https://github.com/facebook/yoga/pull/1829

Test Plan:
- Tested the migrated class directly against facebook/react-native, see the PR [here](https://github.com/facebook/react-native/pull/52998).
- Run: `./gradlew :yoga:assembleDebug` & `./gradlew :yoga:compileDebugSources`

I am not able to run the Java tests in this repo (even before the initial Kotlin setup) – not sure if I am missing something there but any pointers are welcome – it seems like there is some missing configuration. Currently trying with `./gradlew :yoga:test`
