* Moved duplicated code that was constructing a IGeometryProcessing_ApproximateActors::FOptions from a FMeshApproximationSettings to FApproximateActorsImpl::ConstructOptions()
* Added mesh generation options
** bAllowDistanceField - on by default
** bSupportRayTracing - on by default
** bGenerateLightmapUVs - off by default
* Disable creation of physics body for HLOD
* Scale texture size based on grid promotion (higher z grid index -> higher area covered) - Only temporary, will probably switch to a texel density option instead

- extend FImageAdapter to support reading
ModelingComponents::
- Add AssetUtils::ForceVirtualTexturePrefetch(), ::SaveDebugImage() variants to Texture2DUtil
- Add support for debug image writing to WorldRenderCapture and SceneCapturePhotoSet
- FWorldRenderCapture now computes more accurate bounds (visible Components instead of Actors), and does an explicit VirtualTexture prefetch before doing render capture
- FStaticMeshAssetOptions now exposes Nanite settings to allow UStaticMeshes to be created with Nanite already enabled (currently NaniteSettings.PositionPrecision defaults to max)
ApproximateActors:
- IGeometryProcessing_ApproximateActors::FOptions now has settings for enabling Nanite on generated meshes
- ApproximateActorsImpl applies these settings, also enables VT on generated textures if necessary
- FMeshApproximationSettings/FMeshApproximationTool updated w/ new Nanite settings

- FMeshSceneAdapter updates
- if bThickenThinMeshes is enabled, then all instance meshes are converted to DynamicMesh and decomposed to find non-closed regions. Those regions are uniqued into separate meshes. The remaining closed geometry is separated out and kept as instanced.
- various utility functions added to support above
- previous code to explicitly 'thicken' open meshes into solids is removed. Instead unsigned distance is used to determine inside/outside and generate a 1/0 winding number
- instances are now sorted into an octree to speed up winding number evaluations
- If all meshes are closed (or effectively closed via above, ie will return integer winding number) then winding number query can early-out as soon as it finds a non-zero value
- Add hard-normals options in IGeometryProcessing_ApproximateActors (not exposed in MergeActors tool options yet)
- Added hard-normal callucation to ApproximateActorsImpl, and additional profiling
- Allow specification of actual ECollisionTraceFlag options in CreateStaticMeshUtil, instead of just a boolean
- Add FSparseDynamicOctree3::ContainmentQueryCancellable() variant that can early-exit

Add Texture2DUtil::ConvertToSingleChannel(), converts TSF_BGRA8 and TSF_BGRE8 textures to TSF_G8 (based on cast-to-FColor Red channel) to reduce memory usage of a texture
Add CreateDerivedMaterialInstance(), makes a new MIC for input material (either by duplicating or using MIC asset factory)
