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

Fix a lock issue in CopyStructure, bulkdata are not playing well with thread so I prefer not using them for such small amount of editor data.
Removing them remove the following debug assert in LinkerLoad.h that happen when we copy FSkeletalMeshLODModel structure.

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

* First mesh is voxelized by tracing rays in every voxel
* Then voxel faces are clustered in parallel to build continuos cards. Clustering follows voxel distance, card ratio, density and other metrics
* Finally a specificied number of cards is selected per mesh (user parameter). This allows to tradeoff between coverage and runtime overhead
Other:
* Added surface cache coverage view mode for debugging coverage issues - r.Lumen.Visualize.Mode 6
* Fixed r.LumenScene.SurfaceCache.CardMinResolution to be able to go below 2

* Generate surfels directly from the triangles instead of relying on ray tracing, to fix coverage issues on some meshes
* Surfels which are inside meshes (surrounded by back faces) or are too close to geometry are discarded
* New surfel clustering algorithm, which inserts one seed after another and tries to iteratively grow clusters in order to find the best set of seeds. Final step is to reset all clusters and grow all simultaneously from previously selected seeds.
* Cluster growing is based on normal, distance and surfel visibility (don�t cluster surfels near geometry first, as it can cause algorithm to be stuck in a local minimum)
* Runtime sampling has strict culling based on the angle and card AABB. Additionally, the tri-planar blending zone was tightened. This improves performance. 0.62-0.5 ms.
* Added various visualizations and CVars for card generation debugging
* Fixed card visibility bug, where card could influence outside of it�s range due to negative shadow map visibility
