2.Uses the same shading models and dynamic lightings code path on desktop.
3.Remove the division of PI on mobile directional light's color in C++ to line up with desktop in shaders.

Fix virtual textures not updating correctly in debug view modes.
Early depth stencil wasn't being set, meaning that the VT feedback buffer could be overwritted from occluded objects.

Make sure decals are attached before the raytracing scene is created so that the right number of slots can be reserved
Fix miss/callbable shader typo
Fix potential crash when searching for default callable shader index

* Add an early Z test to Nanite rasterization shaders that have programmable pixels
* Opt to always clamp Z when writing to the Depth/Vis Buffer since near clipping is now never a compile-time constant, making the unconditional saturate cheaper than the condition mask (and potentially free in some architectures).
* Combine the code that is common to writing to the vis buffer for both HW and SW into a helper so that the complex preprocessor logic is located in a single location.

- secondary normal is now achieved with two slabs, no fast path for that one which before needed preoject settings anyway.
- coat is only enabled in shader when coverage is >0
- eye is removed from the dynamic case
