- Move VSM parameters into a single uniform buffer; required for base pass rendering.
- SRVs are initialized to dummy data until they are computed during the frame and subsequently updated before any VSM sampling.
- Make names and usage more consistent with other UB bindings in mesh passes
- Direct injection of VSM into translucent volume and fog
- Support VSM sampling in forward lighting shaders
- Enabled and bound currently for translucent forward and single pass water meshes
- Support VSM sampling in sky atmosphere and cloud rendering
- NOTE: Sky atmosphere LUT pass currently executes before BasePass and ShadowDepths so it will not sample proper data and throw a warning. Moving passes around to address this will come in a future commit.

- We should store the Lumen FRDGTexture references in the FViewInfo, rather than converting the textures to external and using IPooledRenderTarget, otherwise RDG can't track the resources to issue the correct resource barriers.
- Resolves missing UAV -> SRV barriers on the volume and history texture resources.

==
* Added instance offset and count to primitive data, along with GetPrimitiveUniformShaderParameters() diffs
* Remaining FInstanceCullingManager& hooks through functions
* Various todo comments to address later
* Calls to (disabled for now) BuildRenderCommands()
* Mutability of FViewInfo in some spots
* Additional instance culling draw params in a few places
* EVertexInputStreamType cleanup
* UseVirtualShadowMaps() feature capability helper function

- View / InstancedView uniform buffers are now bound through RDG directly from the FViewInfo, or created on-demand for cases like jitter-free custom depth.
- Removed most of the custom persistent view uniform buffers. Left one in Lumen to be done in a later CL.
- ReflectionCapture uniform buffer is now bound at the RDG pass level.
