[CL 19846535 by aleksander netzel in ue5-main branch]
* 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.

- Disabling brings a marginal performance increase for CitySample/AncientGame (both have very high primitive counts), so unclear when we would want it on.

* When enabled, translucent surfaces are rasterized again to create a minimal translucency GBuffer, using depth writes and tests to only capture the frontmost layer
* Lumen Reflections are run on the translucency GBuffer, without denoising to reduce overhead (forced to mirror)
* Finally the translucent base pass depth-tests against the frontmost layer depth and applies the high quality reflections. Subsequent layers continue to use the Radiance Cache based reflections.
* Disabled by default due the constant overheads when any translucent surface is on-screen
* New Post Process Volume and Project setting to enable

Fix static mesh commands being rendered in both Depth and DepthWithVelocity passes.
They should only be rendered in DepthWithVelocity.

*) All skin cache entries needing RT geometry update are processed altogether in end-of-frame update whether batch dispatching or not, simplifies the logic.
*) Transition buffers to read immediately after skin cache DoDispatch calls, simplifies the logic.
*) No longer cache the flag to indicate whether RT geometry needs rebuild, the logic is calculated directly when updating RT geometry.

Skip post process material pass when all the pixels will fail the stencil test of the material. Corrects certain stencil test operations from executing full screen when not needed. Saves performance on platforms that are doing the stencil test in the pixel shader with a clip.

* Invalidate Path Traced output when component transforms change (this catches cases that don't re-create a primitive info object)
* Invalidate Path Traced output when light color or intensity changes
* Fix invalidation in a scene only affecting a single view (or view family). Instead of a single boolean, the scene now keeps a counter that ticks on changes and each view remembers the last value of this counter to detect changes.

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.
