This technique is guarded with by a projected settings. It is currently only supported on PC Dx12. This is the initial step for fine grain/per-pixel sorting.

[CL 19470340 by charles derousiers in ue5-main branch]
* Updates to the VirtualShadowMapArrayCacheManager to support the invalidation of cache pages upon removal of dynamic primitives
* Various updates and fixes to support writing dynamic primitives' instance scene data and instance payload data from the GPU
* All these changes are needed by a few existing systems that will be using them soon to render via GPU Scene
(NOTE: This change is a resubmit of 18375369 with CIS fixes that caused it to be backed out)

(cherry pick of 17507631 including later followup fixes in 17526511 and 17542272)
- Disable RDG parallel execution on D3D11.
- Precreate ClearReplacement shaders
- Also add a check to catch other possible issues before it's too late.

Always translate primitive ID for use by mesh draw commands.
Fixes regression from 17093848 which meant that we sometimes earlied out from TranslatePrimitiveId() for a deferred translate that no longer happens.

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.

Move SubmitDrawCommands functionality into FInstanceCullingContext so we may use per-draw auxiliary information collected at Setup step
"UnCulled" bucket will use an optimized permutation that assumes that all submitted items are 'single instance'.

* Translucent surfaces are rasterized with 4x downsampling to mark Radiance Cache probes
* Translucency base pass interpolates from Radiance Cache for reflections instead of ushadowed skylight
* No roughness handling yet, always sampling from mip 0
* Causes full shader recompile

- 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.

- Uses the InstanceCullingLoadBalancer to pre-distribute the work on the CPU to ensure even load.
- Make instance culling use the instance data offset in MDC instead of translating primitive IDs.
- Track single-instance draws separately from instanced to optimize handling (disable culling for single-instance primitives).
