This saves a few milisecond of compile time per shader. This removes the need for occlusion lib when not using occlusion node. To improve detection of uneeded includes, we add a new logging system which output can be fed to mermaid to inspect dependencies. The new dependencies can be inspected using `--log "gpu.shader_dependencies"` Example pasted here: ```mermaid flowchart LR draw_curves_lib.glsl_7298 --> gpu_shader_math_constants_lib.glsl_600 style
