* Card sampling with squared weights instead of cutoff in order to allow surface to leak into tiny areas without coverage
* Bump min static mesh LOD to reduce mismatches between surface cache and geometry
Card placement:
* Move near plane back outside of mesh bounds during capture in order to handle displacement mismatches
* Discard surfels seeing triangle back faces only when sky isn't visible
* New additive card placement, which can be used for continuous LOD. Instead of clustering, it tries to find the best split plane until the entire surface isn't covered.
* Lower voxel and min card size to be able to cover smaller areas and place more cards
* Spawn multiple surfels per cell if they cannot be merged
* Fixed surfel generation and card size

- The number of samples returned is the square number closer to the requested number.
- Updated code paths using the function to request a number of samples close to what they previously got.

* Mostly two sided meshes are assumed to be foliage and forced to be repsented as a cube projection
* Lowered card min density treshold for cube projections

* Added r.MeshCardRepresentation.Debug for surface cache debugging. It skips DDC reads and writes, allows to regenerate per static mesh on demand and appends extra debug visualization data to every generated mapping
* Surfels are now weighted by opacity - ratio of rays which hit in a given cell, and by visibility - how many rays can hit a given Surfel from outside the mesh. This helps to select most important surfaces to cover when hitting limits
* Removed distance constraint. It�s no longer needed when card discontinuities are already handled inside the surface cache sampling code. This allows to generate larger and more optimal cards
* Limit max number of surfels to prevent generation time from exploding, as dense two sided meshes like large trees can generate many more surfels than simple walls

Instead of clearing RadiosityAtlas and skipping Radiosity when switching Lumen to SWRT, voxelize the direct lighting that's been calculated so far and keep the existing Radiosity atlas

FLinearColor has also been modified to make any double->float conversions explicit. Previously all 3D TVector versions were allowed to be implicit and thus could convert TVector<double> => FLinearColor => TVector4<float>.
Fixed up all engine and game casts. Added "//LWC_TODO: precision loss" around any explicit casts that previously were silently explicit and we may need to revisit for precision loss analysis.

Removing them remove the following debug assert in LinkerLoad.h that happen when we copy FSkeletalMeshLODModel structure.
checkSlow(FPlatformTLS::GetCurrentThreadId() == OwnerThread);
It should also prevent a crash with file handle since we cannot lock two different bulk data in separate thread if the two bulk data are store in the same package since they will share a file handle
