- Modify bilinear sample UV to avoid sampling froxels that were occluded in the previous frame.
Perf on console:
- Without MegaLights
- Without HZB culling: 1.7ms
- With HZB culling: 1.1ms
- With MegaLights
- Without HZB culling: 0.9ms
- With HZB culling: 0.5ms

Also removed the word experimental from the LightFunctionAtlas description, as we already use it in production.

The NaN values are output by LumenScreenProbe backlighting and Lumen reflection due to border pixels pixel for pixels having more than one closure.

- Log warnings when building grid exceeds the max number of entries/links.
- ensure instead of check that NumLocalLights and NumReflectionCaptures are less than the primitive limit imposed by FCellWriter.
- clamp NumCulledLightLinks when using bThreadGroupPerCell (unlikely since the first 256 in each cell are temporarily stored in LDS instead of linked list).

- Default settings:
- Use two levels if number of local lights in view > 128 (r.LightCulling.TwoLevel and r.LightCulling.TwoLevel.Threshold).
- One thread group per cell for coarse grid.
- Single thread per cell for fine grid (r.LightCulling.WorkloadDistributionMode).
View with 1K local lights running on console: 0.25ms -> 0.1ms
(based on Ola.Olsson previous work)

- expand sampling froxel footprint (half res) by 3 full res froxels, since during shading we can use samples from any of the half res neighbors.
- expand shading froxel footprint by 0.5 full res froxels to support trilinear filtering.

* Reduced r.MegaLights.Temporal.NeighborhoodClampScale to 1
* Speedup history accumulation when history is out of neighborhood's bounds
* Fix NumFramesAccumulated encoding
* Expose r.MegaLights.Spatial.MaxDisocclusionFrames
* Remove TemporalAdvanceFrame as history is anyway frozen during a pause
