- ShadingFurnaceTest MainPS() OutColor was returning float3, need to return float4 when RGBA texture is bound on Metal otherwise we get validation errors.
- DistanceFieldShadowing; Fetch VS not PS.
- MetalRenderTargetTexture Cube resolve; cube copy to array seems to work as intended, remove asserts to allow this area to be more fully tested.

- Replaced FRW{Structured, ByteAddress}Buffer with TRefCountPtr<FRDGPooledBuffer>
- Replaced ResizeResourceIfNeeded with Resize{Structured, ByteAddress}BufferIfNeeded.
- Replaced FScatterUploadBuffer with FRDGScatterUploadBuffer.
- Removed awkward copy of page table buffers now that scatters are on the RDG timeline.
- Reduced number of uniform buffers created by consolidating within FLumenSceneFrameTemporaries.
- Fixed up const-correctness of FLumenSceneFrameTemporaries to sanity check that resources were not being mutated later in the frame.
- Reduced explicit view creations somewhat.
- Distance fields needs an FDistanceFieldSceneFrameTemporaries to cache RDG resources, but I held off on this due to the number of files it would touch.

- Shaders sampling mesh distance fields must define OFFSET_DATA_STRUCT according to r.DFShadowOffsetDataStructure.
- Also renamed cvar r.DFShadowOffsetDataStructure to r.DistanceFields.OffsetDataStructure since it applies to all techniques sampling mesh distance fields.

* Existing calls to CreateSceneTextureShaderParameters and similar functions use "GetSceneTexturesChecked", which allows for the possibility that they are reached in a code path where scene textures haven't been initialized, and nullptr is returned instead of asserting. The shader parameter setup functions then fill in dummy defaults for that case. The goal was to precisely match the original behavior, which queried the RDG blackboard, and gracefully handled null if scene textures weren't there. This definitely appears to occur in FNiagaraGpuComputeDispatch::ProcessPendingTicksFlush, which can be called with a dummy scene with no scene textures. In the future, I may change this so dummy defaults are filled in for FSceneTextures at construction time, so the structure is never in an uninitialized state, but I would like to set up a test case for the Niagara code path before doing that, and the checks aren't harmful in the meantime.
* I marked as deprecated global functions which query values from FSceneTexturesConfig, but they'll still work with the caveat that if you use multi-view-family rendering, the results will be indeterminate (whatever view family rendered last). There was only one case outside the scene renderer that accessed the globals (depth clear value), which I removed, noting that there is nowhere in the code where we modify the depth clear value from its global default. I would like to permanently deprecate or remove these at some point. Display Cluster is the only code that's currently using the multi-view-family code path, and as a new (still incomplete) feature, third party code can't be using it, and won't be affected.

* Added "BeginRenderingViewFamilies" render interface call that accepts multiple view families. Original "BeginRenderingViewFamily" falls through to this.
* FSceneRenderer modified to include an array of view families, plus an active view family and the Views for that family.
* Swap ViewFamily to ActiveViewFamily.
* Swap Views array from TArray<FViewInfo> to TArrayView<FViewInfo>, including where the Views array is passed to functions.
* FSceneRenderer iterates over the view families, rendering each one at a time, as separate render graph executions.
* Some frame setup and cleanup logic outside the render graph runs once.
* Moved stateful FSceneRenderer members to FViewFamilyInfo, to preserve existing one-at-a-time view family rendering behavior.
* Display Cluster (Virtual Production) uses new API.
Next step will push everything into one render graph, which requires handling per-family external resources and cleaning up singletons (like FSceneTextures and FSceneTexturesConfig). Once that's done, we'll be in a position to further interleave rendering, properly handle once per frame work, and solve artifacts in various systems.

- Point/Spot lights use the same FProjectedShadowInfo for all views. RayTracedShadowsTexture was only generated for the first view. Other views also sampled first view data.
- Store RayTracedShadowsTexture per view in DistanceFieldShadowViewGPUData to avoid using the cached result of a different view.

Storing water in gbuffer and runnign extra lighting pass would be too expenssiv. So instead, when in deferred, single layer water always output the main dir light luminance into a separate 111110 texture.
DF shadow is applied on that texture. DFShadow culling step is cached the first time for a given view in order to be able to reapply DFShadow later with a depth buffer containing water. This save 0.4ms on a base console.
DFShadow is naturaly skipped if the directional light does not have that feature enabled.
When DFShadow is executed, it is basically 0.24ms extra on a base console @ 1080p.
The separated light buffer is an extra 8MB allocated when in deferred.
This only works with deferred for now (forward does not run the reflection/composite pass).
Render target slot assignement is a bit fuzzy but this is a mostly static setup so should be fine. And could change with Strata down the line.
r.Water.SingleLayer.ShaderSupportDistanceFieldShadow is to enabled dfshadow on water for the shaders. Defaults to 1 and will only be enalbed when using deferred and when distance fields are enabled.
r.Water.SingleLayer.DistanceFieldShadow is a runtime toggle of the feature (if enabled the shaders still output to the separate light render target, but that is simply discarded).
Follow up: tile upsample, tile traceshadow, make it work with strata.
Tested shooter and console.

* Removed culled DF object copies during culling. Instead now only indices to culled objects are stored
* Refactored DF heightfield object loads into FHeightfieldObjectBounds and FHeightfieldObjectData
This is a step towards optimizing DF culling and reusing this code for Lumen Landscape culling
Perf Reverb on 2080:
* CullMeshSDFObjectsToFrustum 0.04ms->0.03ms (removed DF object copies)
* Other passes didn't change

- Add r.Shadow.DetectVertexShaderLayerAtRuntime to make it possible to force (for DX11/12/SM5/Vulkan) compilation of vslayer despite RHISupportsVertexShaderLayer being false.
- Set r.Shadow.DetectVertexShaderLayerAtRuntime in WindowsEngine.ini,WinGDKEngine.ini & LinuxEngine.ini.
- Add DoesRuntimeSupportOnePassPointLightShadows to determine support at runtime.
- Fix bug excluding Nanite meshes from DF shadows for local lights if VSM is enabled (now only affects directional lights).
- Add OnGetOnScreenMessages to enable modular generation of on-screen messages in the scene renderer (aimed at transient rendering processes).

FLinearColor has also been modified to make any double->float conversions explicit. Previously all 3D TVector versions were allowed to be implicit and thus could convert TVector<double> => FLinearColor => TVector4<float>.
Fixed up all engine and game casts. Added "//LWC_TODO: precision loss" around any explicit casts that previously were silently explicit and we may need to revisit for precision loss analysis.
