- Removed dead code that once set up additional draw event scopes
- Deprecate FLightSceneProxy::GetComponentName and direct users to GetComponentFName to make it more clear what it does
- Change ComponentName to store the component name (not the owner name)
- Change uses of FName to use FString (for reporting invalid/unbaked lights etc)
- Make ACTOR_HAS_LABELS respect WITH_PROFILEGPU to enable profiling in Test & Shipping

- Enables turning off non VSM for more cases.
- Only send primitives with dynamic relevance down the dynamic subject path.
- Optimization: cache IsNaniteProxy flag on FLightPrimitiveInteraction.
- Fix the MaxNonFarCascadeDistance calculation to not include DF cascades.
- Skip SM allocation for uncached SMs without subject primitives.
- Add flag bSupportsGPUScene to FPrimitiveSceneProxy and helper to set up EnableGPUSceneSupportFlags (also turns on bVFRequiresPrimitiveUniformBuffer)
- Add error check to make sure bSupportsGPUScene is not set unless all VFs actually supports GPU-Scene

Disable by default for now as this can add non-negligeable voxelization cost due to inaccurate shadow view culling.

1. Nanite meshes are not longer marked as always visible, and will go through the standard rendering culling / pipeline.
2. Add coarse frustum culling using the already existing scene octree.
3. Remove Distance visibility bit array, and converted only usage to using the visibiliity map. (Spoke with Kenzo about this, the original was put in due to differences between distance a vis flags, but this has been fixed)
4. Optimized Frustum culling methods across the board.

Page allocation part is a fairly minor benefit in most scenes but can occasionally make a big difference.
Projection early-out is a pretty uniform benefit all the time, especially with SMRT.

The intention is that lights will eventually take this path automatically when no geometry that can't be rendered into a VSM is present (or no such types exist anymore in the engine).
Fix a few cases where assumptions are made about VSMs only existing if a conventional shadow map exists and so on.
Allow Lumen to consider the VSM result "complete" if valid and no shadow map is present.

Run a compute job that packs most commonly used instance data (LocalToWorld matrix and some other bits - 80 bytes) into per-instance vertex buffer. Vertex shader does not have access to GPUScene and instead loads instance data from a per-instance vertex buffer. If it needs more primitive/instance data than available then it will load it from Primitive UB, binding unique uniform buffer and breaking auto-instancing. Pixel shader has a full access to a GPUScene
There are 3 ways how FSceneDataIntermediates gets populated
1. PrimitiveId + GPUScene (Desktop)
2. Per-Instance data + Primitive UB (Mobile)
3. Primitive UB (auto-instancing disabled)
Details for GPUScene specific vertex inputs and access to FSceneDataIntermediates are hidden behind a macro:
VF_GPUSCENE_DECLARE_INPUT_BLOCK
VF_GPUSCENE_GET_INTERMEDIATES
FSceneDataIntermediates is now stored in FVertexFactoryIntermediates, FMaterialVertexParameters. Added a few GetPrimitiveData() overloads that allows you to access PrimitiveData depending on current context. Removed most of the cases where GetPrimitiveData() gets used with PrimitiveId.

- 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
