- Move translucent injection outside the loop rather as it shares state and doesn't need barriers between it. This had already been done for unshadowed lights but this implements it for shadowed lights as well.
- Implement VSM one pass projection (still default off) even when clustered shading is not enabled. Has two paths in the regular light loop:
1) If another effect (ex. light functions) needs to interact with the screen shadow mask, a VSM composite path is inserted that does a quick copy from the one pass projection shadow mask bits
2) If only VSM is needed for the light, the lookup is rolled directly into the deferred lighting pixel shader, eliding the screen shadow mask entirely
Especially in the second case this significantly cuts down on GPU idle time and g-buffer bandwidth, improving the performance of scenes with small local lights

Fixed include paths to be relative to the private or public folders.
Hid or removed includes that reached into other private module folders.
Updated PublicInclude paths when necessary.

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.

Clients outside Renderer should use the default view, or the self managed FShaderPrintData (improvements to that incoming).

* 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.
