C++ style enums 1/N: Generator (#1384)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1384

X-link: https://github.com/facebook/react-native/pull/39446

This adds logic to the enum generator to generate C++ style scoped enums.

This gives us a few nicities over C enums, even if both must exist:
1. We can add types and keep unsgined enums directly in bitfields
2. Style/readability
3. Avoiding implicit int conversion
