Remove config drilling (#1378)

Summary:
X-link: facebook/react-native#39404

Pull Request resolved: #1378

We thread a config through the root node, to every function, that we don't actually use (with the exception of `canUseCachedMeasurement` in the previous diff which was passing root `pointScaleFactor`).

Since the model is currently per-node config, this only creates redundancy/confusion.

I do think we might want to make some more global/layout-pass scoped configuration in the future, but likely not with this sort of drilling.
