Upgrade Gradle setup (facebook#1084)

Summary:
Trying to dust off the build setup and make it work again with a modern Android Studio / JVM.

Removing all JCenter setup, too, as this is no longer supported.

Pull Request resolved: facebook#1084

Test Plan:
`./gradlew :yoga-layout:assembleDebug` works already.
Looking if CI here likes this.
