- preparational step to enable HZB culling of invalidations in an uniform way.
- also add FComputeShaderUtils helper to set up an indirect dispatch.

* First all cards are allocated to a temporary atlas of fixed size set by r.LumenScene.CardCaptureAtlasFactor
* After cards are captured into temporary atlas, they are compressed into final BC compressed atlas. Compression can be disabled with r.LumenScene.SurfaceCache.Compress
* Atlas clears were also converted to support clearing compressed surfaces
* Atlas capture operations work on uploaded rect list, instead of a GPU generated card list
* Renamed r.LumenSurfaceCache.* to r.LumenScene.SurfaceCache.*
* Renamed LumenSceneLighting.usf to LumenSurfaceCache.usf
* Renamed LumenScenePrefilter.cpp to LumenSurfaceCache.cpp
Cuts down VRAM memory usage by 160mb
Compression performance on console: ~0.18ms for 1M texels (~0.9ms with UAV aliasing path, which is currently disabled due to missing pieces in RHI)

- Views are cached on RHI transient resources; view renames are no longer necessary.
- RHI Transient resources utilize a single cache per heap keyed off of the descriptor + offset. Resource caches and heaps are garbage collected.
- CPU performance is effectively equivalent to the existing pooled resource method.
- Added common RHI transient resource allocator implementation in RHI core; significantly reduces the amount of platform code.
- Resource aliasing overlaps are tracked by the RHI and submitted through an acquire operation.
- Fixed D3D12 implementation to support multi-GPU.
- Removed condition that excluded small (<64k) buffers in the transient allocator.
- RHI validation now checks that resource overlaps are valid; i.e. if an overlap occurs between resource A and B during an acquire of B, validation checks that A has been discarded.

- 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.

- Added GetLoadActionIfProduced helper function.
- Made GetPooledFreeBuffer attempt to reuse the existing allocation.
- Disable load action validation when SkipRenderPass is specified.
