- Removed scene render mem-mark among others. MemStack usage is now restricted to local scopes with known marks.
- Render resources with destructors are allocated using the FSceneRenderingBulkObjectAllocator on FSceneRenderer, which is deleted when the scene render is.

The refactor to get rid of the FSceneTextures and FSceneTexturesConfig global singletons has also been preserved. The FViewFamilyInfo is used to hold those structures, so client facing API functions that lack a scene renderer reference can still pull the FSceneTextures[Config] from the view family pointer. All other scene renderer state has been moved from FViewFamilyInfo back into FSceneRenderer.

* 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.

Local light shadows are supported on mobile forward and deferred, need to enable full depth prepass to generate the ShadowMaskTexture.
Remove the 4 maximum local lights limitation on mobile forward.
Remove the "High Quality Reflection" on mobile forward.
Disable simple lights on mobile forward.

- 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.

[CL 19669626 by tiago costa in ue5-main branch]
- Shadow PreViewTranslation and ClipmapOrigin become full LWC tile/offset values on the GPU
- In most cases, the camera's and shadow's PreViewTranslations can be subtracted on the GPU to produce a regular-range value to transform from PrimaryView.TranslatedWorld to ShadowView.TranslatedWorld
- Miner cleanup and improvements to SMRT trace loop
- Remove special case for ortho matrices disabling PreViewTranslation in FViewMatrices
- Remove broken static function local and associated cvar r.PreViewTranslation

- Add bHasDeformableMesh to FPrimitiSceneProxy to declare if the meshes are deformed, e.g., skeletal mesh, to be able to catch this case.
- also fix incorrect tracking of revealed primitives (causes invalidation errors with missing shadows when meshes are culled on the CPU).
- Add cvar switch to turn off the new behavior (for emergency use) r.Shadow.Virtual.Cache.DeformableMeshesInvalidate (defaults to 1)

- set VSM to use distance culling for non nanite by default (r.Shadow.Virtual.UseFarShadowCulling).

- 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.

Requires two additional compute passes post-culling to compact the draw command instances.
This feature is not currently supported on mobile platforms; more work is required to make instance compaction work with mobile vertex buffers.
Updated ISM to use order preservation for meshes that render with a translucent material
