This aims to preserve the surface area during simplification. If area is lost, open boundary edges of the mesh are dilated to compensate. This is useful for foliage that tends to thin out in the distance if not enabled.
Also include misc fixes:
Collapses that completely remove disjoint triangles have an error of the area of what was removed.
Would not alias 0 and -0 verts due to binary comparison.

- If a static mesh is detected to use Nanite or a project is configured to use Virtual Shadow Maps and SM6 is not in the project settings, show a warning that SM6 needs to be enabled.
- Both cases only warn if the project was already configured to use a D3D platform.
- Added a UI option for enabling Nanite in project settings.

Removed redundant private include paths from build.cs files.
Fixed include paths to be relative to the private or public folders.
Hid or removed includes that reached into other private module folders.
Updated PublicInclude paths when necessary.

Artists can import/reimport(/new file)/remove nanite hi res data from the content browser context menu.
Artists can easily see in the static mesh editor if the nanite hi res data is generated or imported.

* 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

These both trim detail from the Nanite data that is stored to disk and can be used to optimize disk size after import. Should be a super useful tool late in production.

Changed fallback settings to be largely error based with new property FallbackRelativeError.
Nanite builder will now provide the LOD fallbacks for all autogenerated LOD levels which is far faster than generating them from scratch.

* 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
