r.ShaderPipelines
r.Material.ExcludeNonPipelinedShaders
Both cvars are currently disable on WindowsEngine.ini which make them also disable when we cook for consoles. ExcludeNonPipelinedShaderTypes is currently used only at cooking time when we compile shaders which is currently returning false, since the value is disabled on windows. Making those cvars use FShaderPlatformCachedIniValue, will allow to have specific platform value when cooking for a specific target. Moving r.Material.ExcludeNonPipelinedShaders to the defaultengine.ini file to keep it disable for the moment and not affecting shader key string. Will enable it progressively on console later.
r.Shaders.RemoveUnusedInterpolators
Make that cvar platform agnostic, since it will be used in on other consoles eventually. Platforms supporting the stripping of unused interpolators will check the same flag (CFLAG_ForceRemoveUnusedInterpolators) to enable it. Since windows can run opengl, and stripping is not supported on that shader platform, add extra logic to exclude the flag.
-Make the RHISupportsShaderPipelines function access a real DDPI attribute and not just test if we are not on mobile. Will need this to be able to have stripping unused shader interpolators on Switch.

[CL 26038736 by serge bernier in 5.3 branch]
What:
* Add data support flag for NNE shaders so platforms can opt in to the NNERuntimeHlsl shaders compilation.
Tests:
* NNE smoke test + style transfer demo on: win64 editor, win64 packaged

Several PRs have been filed on GitHub for DXC (PR 5017, PR 5020) and SPIRV-Tools (PR 5107).
Integrated from CL 23998474.
Workaround for DXC rewriter bug: Have member function definition inside struct declaration.
Integrated from CL 23976367.
Explicitly initialize TNaniteWritePixel members as empty structs expose further bugs in SPIR-V backend of DXC.
Rebuild ShaderConductor for Win64, Mac, and Linux (Empty struct fix).

It's disabled on Android because some android devices don't support dual src blending, and it's disabled on IOS because it doesn't work with MRT.

- RHISupportsMultiviewport made to work on relevant shader platforms.
- RHISetStereoViewport implemented
- Unused outputs removal fixed to always consider viewport index used.
- Renamed confusing terminology (multiview -> multiviewport).
- Added a CVar (vr.MultiViewport) to force disable
- Added a canvas output to know the method in non-Shipping
