* 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)

[CL 18375424 by jamie hayes in ue5-release-engine-test branch]
- Add some dither noise to both the SMRT result and the shadow mask lookup to minimize banding
- Fall back to a single sample VSM lookup (with a generous static bias) when overflowing the number of lights in one pass projection path
- Fix clamping issue with page dilation that was setting extraneous pages with point lights
- Fix SMRT issue with local lights jammed right next to geometry viewed at a distance
- Separate settings for page dilation for local and directional lights
- Add simple debug output for # lights in one pass projection
- Remove some dead code/parameters

This mainly solved missing body geometry during one/two frame during the WU sequence.

* Every HWRT trace marks sampled pages with a current frame index, by writing to a last used page array
* There are two arrays, one for always resident pages and one for high res pages. This allows to prioritize high res updates (things visible in reflections)
Controlled using r.LumenScene.Lighting.Feedback 0
No measurable impact on performance.
Misc:
* Added various update rate visualizations to visualize feedback and page lighting updates
* Removed DIFFUSE_TRACE_CARDS leftover from early Lumen days
* Disable feedback when Lumen surface cache is frozen (for debugging purposes)
* Disabled feedback in DF tracing as anyway it worked only in visualization mode

- Use InstanceSceneData instead of caching local transform (r.CachedRayTracingInstances.CacheLocalTransform).
- Lazily cache world trasform (r.CachedRayTracingInstances.LazyUpdate).

* Added FLumenRadianceCacheHardwareRayTracingCS and FLumenReflectionHardwareRayTracingCS that use TraceRayInline.
* Added LumenHardwareRayTracingHitDataBuffer to store hit group user data for access in compute shader.
* Temporarily expose number of segments from FRayTracingGeometry for building hit data buffer.

Bonus: Saves about 1.1 MS in the current branch.
