Revert "Add DepthNormal() mode to lit shaders, this seem the most straightforward way to do this, shaders with just Depth() usually have a shared shader with no-color no-material output, legacy shaders rebuild normals from depth, not rendered in depthnormals mode" This reverts commit 1de87df502b99a787b40381cc6b52988f9dae6bc. Use Depth MODE instead of DepthNormals for DepthNormals
