* 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.

This avoids to define STRATA_ENABLED as 'env. define' for all global shaders needing a Strata specific path.

- Add some dither noise to both the SMRT result and the shadow mask lookup to minimize banding
- Fall back to a single sample VSM lookup (with a generous static bias) when overflowing the number of lights in one pass projection path
- Fix clamping issue with page dilation that was setting extraneous pages with point lights
- Fix SMRT issue with local lights jammed right next to geometry viewed at a distance
- Separate settings for page dilation for local and directional lights
- Add simple debug output for # lights in one pass projection
- Remove some dead code/parameters

This allows to remove the hair emissive CVar and avoid any cumbersome workflow. The hair material pass run now in two pass on platform that don't require an RT during PS pass. A first pass for emissive, and a second pass for non-emissive. This allows to keep non-emissive cost low, and have the flexibility of emissive.

- Add VirtualShadowMapId to forward light data, removing the per-view remapping table. Should fixe a few multi-view/split-screen bugs.
- Minor cleanup of PCF subsurface path; remove dead/broken code.
- Fix up blending of light attenuation into screen shadow mask; disable CSM fading when VSMs are enabled.
- Fix OnePassProjection flag when VSMs are disabled

- Refactored RDG to support free-threaded execution of passes.
- Refactored renderer to use specific RHI command list variants in pass lambda. Immediate command list passes are forced to stay on the render thread, while other variants can be parallelized.

- add IsSupported to ShaderDebug API
- cleaned up some potentially unsafe uses of IsSupported/IsEnabled to guards shader parameter setting
- added AddOBB to ShaderDrawDebug
- Removed restriction that limited shaderdraw to editor-only

Major SMRT optimization. Adaptive 7 rays per light with rough penumbra detection. Quality appears to surpass 1rpp with denoising.
