Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/41347 X-link: https://github.com/facebook/yoga/pull/1453 This follows the previous patterns used for `Gutters` and `Dimension`, where we hide CompactValue array implementation from `yoga::Style` callers. This allows a single read of a style to only need access to the resolved values of a single edge, vs all edges. This is cheap now because the interface is the representation, but gets expensive if `StyleValuePool` is the actual implementation. This prevents us from needing to resolve nine dimensions, in order to read a single value like `marginLeft`. Doing this, in the new style, also lets us remove `IdxRef` from the API. We unroll the structure dependent parts in the props parsing code, for something more verbose, but also a bit clearer.
