- Fixed GBufferPostDecode to correctly decode custom data according to shading model.
- Fixed Reflection Env PS to apply the correct normal and roughness on the top clear coat layer lighting.
- Fixed ClearCoatBxDF to not apply anisotropy onto the top layer, for its roughness to not affect the bottom layer and added safe ranges to avoid NaNs.
- Fixed SSRReflection to trace for the top layer for clear coat. It will slowly lerp towards tracing for the bottom layer according to the clear coat parameter.

- only a single uint used for normal, roughness is moved on the classification state free bits
- renaming Normal to WorldNormal
- Removed duplciated classification code from Basepass.
- AO is now gamma 2.0 compressed.

- Removed use of gbuffer in SingleLayerWater passes
- SLW compute envbrdf in the compositing pass from strata water material.
- It is no longer needed to use the classification buffer, avoiding an extra classification pass just for water
- To do this, the SSR pass then also read the water BSDF directly
- Made room in the top layer data for SSS data coming soon

- Basepass shader no longer expoert all rendertarget. Only scene color, preshado, velocity if enabled.
- More decoupling from GBuffer. Now normal gbuffer is not used by any of SSAO, DFAO, HBAO and SSR. Achieved with permutations.
- Strata header now contains PrecShadow bits.
Shooter game compiles on pc and console. Tested with Strata disabled.

Contains all work on Lumen since shipping Reverb in March:
* New Opaque Final Gather with higher quality in clean architecture and better performance
* Improved global tracing which reduces leaking
* New basic Reflections pipeline which respects material Roughness
* New HZB traces that are more accurate at tracing against the depth buffer
* Hardware Ray Tracing paths for Lumen shadowing and Final Gather
