Remove YogaLayout ViewGroup (#1318)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1318

We deprecated this as part of the Yoga 2.0 release. The last version is still present as part of the `release-v2.0` branch, and was still published, but we are not carrying the code forward. This removes it.

There are a couple followups here:
1. The top-level organization (e.g. a gradle-specific directory called `build-logic` in a multi-language repo) can and should be cleaned up. Yoga Java bindings should be condensed to the `java` folder.
2. We no longer have a sample app excersizing the bindings. We should resolve this by getting the JNI binding UTs working in OSS again.
