- 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.

- Removed awkward AfterTasks lambda. Looks vestigial and isn't worth the code complexity.
- Consolidated depth-related config data into a struct instead of loose variables on the deferred shading renderer.
- Moved some internal functions to static instead of class members.

Contains all work on Lumen since shipping Reverb in March:
* New Opaque Final Gather with higher quality in clean architecture and better performance
* Improved global tracing which reduces leaking
* New basic Reflections pipeline which respects material Roughness
* New HZB traces that are more accurate at tracing against the depth buffer
* Hardware Ray Tracing paths for Lumen shadowing and Final Gather

- Shaders are searched by TypeName and PermutationId, so move those fields out of FShader and into separate arrays inside ShaderMap, to reduce cache misses while finding shaders
