Expose box sizing getters and setters in Yoga (#1701)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1701

X-link: https://github.com/facebook/react-native/pull/46630

I would like to write some tests for box sizing that will drive a lot of my development as I implement content box. To do that, I need this publicly exposed. Obviously not that ideal since this currently does not do anything. Maybe we can name the value in such a way that its clear it is in development?
