Remove usage of Dimension arrays and YGDimension as index (#1402)

Browse Source 
Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1402

X-link: https://github.com/facebook/react-native/pull/39567

This change hides away most usages of YGDimension as an index. We do this for a couple reasons:

1. Right now the style interface may return a full array of resolved edge or dimension values, as a CompactValue. As we abstract away from CompactValue, and move towards ValuePool, this will no longer be the internal interface, and cheap to return. We instead change the interface to return a single value at once, which lets us resolve values lazily.

2. As we move internal usage to scoped enums, enums are not implicitly convertible to intergers (broadly a good thing). Hiding the enum as index prevents the need for callers to cast or convert to underlying.

Instead of making a new version of `IdxRef` for this, I converted to a more traditional setter. I will be making similar changes later for other styles, when I hide CompactValue from the public interface.

To review I would recommend filtering to changes in `xplat`, or viewing this in a single one of the OSS PRs exported. Everything apart from the below 20 files is a mirror.
