This is an enum to say which target to reduce to for the fallback. It makes the default "Auto" which gives us more ability to change the default heuristic without needing to change uproperty defaults.
Along with this added r.Nanite.Builder.FallbackTriangleThreshold. Any mesh with source triangle count less than this threshold uses the source triangles directly for the fallback.

The threshold in LOD generation to check the quality of the LOD was to small.
It has been update to sqrt(3) i.e. the reduced mesh must stay in the bounding sphere.

The spikes seems to not happen any more with the new simplification algorithm.
Whatever, the bounding box of the simplified mesh is compared to the original mesh. If the new bounding box is larger, a message is output.

-Nanite-specific settings for tangent and degenerates are no longer also applied to the non-nanite mesh LODs on the same mesh.
-100% fallback meshes now have identical tangents to input mesh. Don't skip the tangent generation in StaticMeshBuilder for these meshes and don't recalculate tangents in Nanite builder.

Tangent generation now also respects the Nanite project setting, not just the per-mesh setting.

Add some CPU trace for interchange task, fbx translator, skeletalmesh factory.
Fix issues with UVs count crashing when there is no UVs layer.
Add generic pipeline asset to always cook in the plugin game.ini config file.
Make sure we use only half of the worker thread to avoid deadlock because there is no worker thread available.

Switched FDynamicBVH to use greedy insertion because branch and bound perf significantly degrades with heavily overlapped leaves.
Added closest point queries using branch and bound.
FBounds is now templated as TBounds.

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.
