Deprecate YGConfigSetUseLegacyStretchBehaviour (#37117)

Summary:
X-link: https://github.com/facebook/react-native/pull/37117

Pull Request resolved: https://github.com/facebook/yoga/pull/1265

This deprecates `YGConfigSetUseLegacyStretchBehaviour` and `YGConfigGetUseLegacyStretchBehaviour`and points users to errata APIs instead. Using the C API will fire deprecation warnings, which should create errors in builds with `-Werror`, though they can be ignored if truly needed (like we do with the language bindings which need to expose their own deprecated interface).
