Remove private headers exposed by podspecs (microsoft#1252)

Summary: X-link: facebook/yoga#1252 Pull Request resolved: facebook#36993 Fabric relies on the private C++ internals of Yoga. This creates a conundrum in the open source build due to how header creation in Cocoapods works. 1. The default mechanism of specifying public headers needs to include the private headers for them to be made usable by fabric (by default) 2. Cocoapods will roll up all of the public headers when importing a module facebook#33381 fixed the Fabric Cocoapods build which ran into this. React Native relies on FlipperKit which relies on YogaKit, which in turn finally imports the Yoga podspec. Because YogaKit may use Swift, we can only expose the public Yoga C ABI. The first solution in that PR was to allow RN to access Yoga private headers, but this was changed to instead make all Yoga headers public, and to add ifdefs to all of them to no-op when included outside of a C++ environment. Talking to Kudo, we should be able to change back to the earlier approach in the PR, to instead expose the private headers to only RN. This lets us avoid exposing headers that we ideally wouldn't be, and lets us avoid the messy ifdefs in every Yoga header.
