These flags (like `'HIDDEN', 'SKIP_SAVE', etc.) mean the same thing when used on enums and non-enum properties. Now they actually use the same description definition in the source code, ensuring that any improvements will apply to both. No changes to the actual messages. Just using them for both enums and non-enum property flags. Pull Request: https://projects.blender.org/blender/blender/pulls/118036
