Summary:
I'm actually quite excited about this one!
No more buck shelling out for building the Yoga AARs/JARs via Gradle. It's now
all done via Gradle.
This commit is the only one that should actually change anything about the entry
points to the gradle builds and release process. **So if anything goes wrong
with the next release, reverting this one here should be enough!**
