Replaces all usage by the the gpu_shader_math equivalent. This is because the old shader library was quite tangled. This avoids dependency hell trying to mix libraries. Changes are split into isolated commits until I had to do mass changes because of inter- dependencies. Pull Request: https://projects.blender.org/blender/blender/pulls/113631
