features: remove GA features
This removes all feature definitions that were marked for removal in 1.25, with some exceptions: - some features were marked for removal in 1.25 although they only graduated to GA in 1.24 - that seems too soon, so the comment was updated instead - CSIVolumeFSGroupPolicy and PodDisruptionBudget are still used in the code, so removing them will be more work and was deferred
