DRAFT: Use reference Yoga CMake build for libyogacore (#1291)

Summary:
X-link: facebook/yoga#1291

Pull Request resolved: #37371

**Draft:** This is a draft change that I cannot make a draft in Phabricator because I want to export it to GitHub.

This makes React Native use `libyogacore` as provided by Yoga's reference CMake build. This in turn matches Yoga in the OSS RN build to the same compilation settings we use internally. It also means less differences between all the builds (maintainability win).

This does not yet do the same for the Yoga JNI bindings.˜˜

[Android][Changed] - Use reference Yoga CMake Build
