On the the skel mesh component is used to retrieve the mesh object. This needs to be fixed in a subsequent CL.
Skel. mesh triangles are processed section by section. This is inefficient when section are small. Ideall all section should be process at once. Also, on the the used section (i.e., having roots attached to) should be process. This should/could be addressed in future CL.

Uniform Buffer struct initializing now just use a global resource/sampler to instead of calling the getter function.
Adding bindless support to FShaderResourceParameter.

This is simply done by an added PreviewColor on the FStrataData that flows between the node to be able to work with parameter blending or StrataTree BSDF composition. Can be updated later to anything else.

* When r.Lumen.ScreenProbeGather.DirectLighting is enabled, all local lights will be rendered by Lumen (if enabled)
* With 8 shadowed lights on screen, Lumen Direct Lighting costs .4ms, while Cached Shadowmaps cost (1.3ms), Distance Field Shadows are (1.8ms) and Virtual Shadow Maps (6.1ms) on a 2080 TI at 1080p resolution
* IES profiles and Light Functions are not yet supported, nor is Hardware Ray Tracing
* Shadowing and light attenuation resolution is tied to Screen Probe Gather downsampling so quality becomes poor with High GI settings (32x downsampling)
* r.Lumen.ScreenProbeGather.LightSampleResolutionXY controls how many light samples are traced per Screen Probe, with lights being selected with equal probability. More lights overlapping causes more noise, not increased GPU cost.

This attribute of point and spot lights was previously ignored. Additionally, unify treatment of point and spots so their shadows behave consistently with one another (as is already the case in path tracing).

- Added FShadowSceneRenderer to handle shadow rendering (transient) work - intended to take over more responsibility from here on.
- Added cache invalidation when lights are removed from the FScene (required as ID / cache key may change)
- Modified caching scheme to drop cache entries when caching is disabled.
- Changed local light footprint estimation to depend on the scaled resolution (screen percentage)
- Moved light location data and test to per-light cache entry (rather than per-shadow map)
