Vulkan backend has recently switched to a render graph approach. Many code was left so we could develop the render graph beside the previous implementation. Last week we removed the switch. This PR will remove most of the unused code. There might be some left and will be removed when detected. Pull Request: https://projects.blender.org/blender/blender/pulls/123422
