0267d53323 DisplayCluster: Virtual Shadow Map cache can optionally be allocated per view, and enabled that feature for Virtual Production. Significant performance win by avoiding constant cache thrashing when rendering multiple families. Frame time goes from ~45 ms to ~26 ms for Valley test scene (Node 2), GPU bound in both cases. Separate cache per view isn't implemented for split screen views (single view family with multiple views), but Virtual Production doesn't use that, and support for that could be added in the future.

b19bb6be2f UE5_MAIN: Multi-view-family scene renderer refactor, part 1. Major structural change to allow scene renderer to accept multiple view families, with otherwise negligible changes in internal behavior. 
* 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.

3cb3050f56 UE5: Fix for occlusion query startup assert when using the mobile renderer. Reverting occlusion query fence implementation to original code for all use cases besides DisplayCluster, the case we needed to optimize for multiple view family rendering (the optimization saves 8 ms in the Virtual Production City demo). Longer term, we might want a more robust refactor of the code to handle both cases, but we need to unblock mobile in the short term.

3a9944fb7c DisplayCluster perf: made it so scene occlusion queries are added to a queue based on the UniqueID of the first View in the ViewState, so in scenarios where there are multiple view families rendering, a given view family can wait on its own query fence (next frame), rather than the fence for the previously rendered view family in the current frame. This avoids an unnecessary stall waiting on results that aren't actually going to be used, saving up to 8 ms in stalls in a Virtual Production test case. If the queue fills up, one fence is automatically pulled off the queue and waited on, so there is room to push a new fence.

b5219b04e6 Remove Geometry Shader path for point-light shadow rendering, disable point light shadows if VertexShaderLayer is not supported (at runtime). 
- 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).
