Cleanup: remove duplicated shaders that only added clipping checks

Originally I wanted to avoid adding draw manager specific ifdef's all
over generic shaders however this isn't needed in so many places.

Also there are shaders that are only used by the draw manager so
duplicating them only to have the original unused doesn't make sense.
