- Fix operand order of manual stencil test used when Nanite renders custom depth (reference value should be on the left hand side)
- Force compositing of a post-process material's output with the input when manual stencil test is enabled to fix corruption in discarded regions.

- Coverage over the background can be override from the root node when AlphaCompiste blend mode is selected. If not plugged in, coverage of over brackground is off and regular blending is used.
- Decals only support translucent, composite and modulate. Normal is ignored when using CompositeAlpha (seen somewhere)
- Light functions can only be opaque so nothing to do in this case.
- UI domain tested with all blend mode
- Material attribute aslo tested
- Fixed many of issues with blend mode defines, being forced, etc.

1. Postprocess can access path tracing buffers (raw/denoised radiance, albedo, normal, variance) with unique material node `PathTracingBufferTexture`.
2. Output in MRQ is also supported.

- Completely changed the way we evaluate and represent the material topology.
- A topology is now represented as a tree to allow any horizontal/vertical operations (almost like a kdtree).
- This allows for correct translucent material coverage/transmittance evaluation, as well as correct BSDFs luminance weight (finally).
- All the operations to be able to do that are expended in HLSLTranslator instead of letting the compiler handle it (otherwise was too slow, leading to bugs and could not even debug shaders). This means no conditional BSDF packing.
- There is no more Material/layer/BSDFs array: only a Tree or operators, some of them being BSDF at leaves.
- Parameter blending has also been updated: when enabled on a node, it will be forced on all the oprator child / in the sub tree.
- Parameter blending is applied on an inlinedbsdf on the StrataData. When it is the root of the parameter blending subtree, it is promoted to a fully fledged BSDF operator node to allow other regular operators.
- The inlinedbsdf is not longer in premultiplied mode. Horizontal/Vertical/Add parameter blending operators have been updated to reflect that. This allows for simpler/unified/clearer code.
- Vertical blending now uses the new simple "layering of two slabs with uncorelated coverage" math I have RnD'd. See GetVerticalLayeringInfo in ShadingCommon.ush.
Follow up to this CL:
- CompileStrataBlendFunction should use parameter blending.
- Add more compilation debug output
- Update material vizualisation
- Fix Rough refraction
- Fix decals
- Fix debug probes
- Pack FStrataBSDF
- Move all StrataCompilationInfoCreateSingleBSDFMaterial into into the strata tree and rework cost evaluation and material LOD
- Expand graph visit such as UpdateBSDFWeightAfterOperatorVisit to be specific to operators for the compiler to have to do less search to inline what we know already
- Fix STRATA_TODO: operation using parameter blending are not actually discarded so they still occupy a pot in the opeartion arrays in the compiler and in the shader also.
