- Allow for per-project override in a project's platform's config folder (this is merging with my other work on per-project SDKs and validation of multi-target builds)
- More versions will move over after this

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.

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

These will allow hardware device identifiers to set flags for themselves to identify some common traits that they have, as well as check what kind of support they have. These are config flags, so if a game wants to change what they support for a given input device they can easily do so, as well as add in some custom hardware types if desired.

- The config section is the DDSPI ShaderFormat of the shader platform
- BindlessResources and BindlessSamplers can be set independently
- The cvars still exist and will take precedence over the config settings.
- Renamed RHIGetBindlessResourcesConfiguration/RHIGetBindlessSamplersConfiguration to have the word "Runtime" in them to reflect that they should only be used at runtime and not when deciding if it's enabled for a shader.

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.

- Implemented for D3D11 and D3D12, as Mobile Multi View (MMV) fallback on both.
High level summary / notable changes:
- preview shader platforms will get the necessary properties from the desktop shader platforms used to display them
- stereo render target manager will get informed which shader platform the engine is currently using
- regularized somewhat what happens when the editor's preview platform changes (enabling/disabling and activating/deactivating). (Preview system is confusing because it's tri-state: preview platform can be set but not active, which is the same as it not being set). More code can be de-duplicated there.
- Multiview will be considered disabled (for scene textures at least) if, despite ViewFamily requiring it, no View actually has it enabled.
- Patched a bunch of shaders to account for texture array RTs used for MMV (and MMV fallback).

ComputeFramework: Disable on Vulkan platforms using DataDrivenPlatfomInfo
Do this until we fix user defined structures that don't obey Vulkan packing rules.
