Remove YGNodeMarkDirtyAndPropagateToDescendants (#1448)

Summary:
X-link: https://github.com/facebook/react-native/pull/41305

Pull Request resolved: https://github.com/facebook/yoga/pull/1448

This should not be part of Yoga's API. If benchmarks want to do this, they still can (though I don't know the ones we have for it are super valuable).
