Core - Added support for assigning a TObjectPtr<T> to a TScriptInterface just like you'd expect from a raw Object*.
Actor - Making a version of GetComponents that will work for TObjectPtr collections. Additionally fixed several places in the engine where we're forcing the template parameter instead of allowing it to be determined automatically - which forced me to leave one of the GetComponent implementations, but I think we aught to remove it. e.g.
Don't Do
TArray<UPrimitiveComponent*> PrimComponents;
Actor->GetComponents<UPrimitiveComponent>(PrimComponents);
Do
TArray<UPrimitiveComponent*> PrimComponents;
Actor->GetComponents(PrimComponents);
Slate - Introducing support for collections of TObjectPtr<T>'s being used as source lists for the STableView.

Crash when trying to run Merge Actor Tool using new Approximation and replace an already generated mesh
Will now generate the assets in temp packages & replace the original ones after.

* Fixed copy paste error causing the wrong texture size to be computed when using the approximate actor merge method along with an automatic texture size based on the mesh draw distance

Supports either:
* From texel density
* From expected mesh screen size
* From expected mesh draw distance
Compute best texture size, taking UV map waste into account.
Currently only supported by the Approximate Actors merge method, to be integrated in the ProxyLOD later.

* 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

- Add FImageAdapter, wraps TImageBuilder of different types and provides a consistent interface, so that other code doesn't need specializations for each image type
- FMeshSceneAdapter now supports the ability to detect and thicken "thin" meshes, by flattening the instances into unique mesh copies (generally necessary due to scaling). Can also now return statistics about the mesh scene, return a full flattened mesh (for debugging), and automatically generate a "closing mesh" that can help to cap off the base of mesh assemblies when trying to generate a solid/etc.
ModelingComponents:
- FWorldRenderCapture now writes via FImageAdapter instead of an Image4f
- FSceneCapturePhotoSet now stores less data for photo sets. BaseColor/Emissive/WorldNormal are 3f, Roughness/Specular/Metallic are 1f
- IApproximateActors and implementation now support optional base-capping, occluded mesh removal, geometric-tolerance simplification, thin mesh auth-thickening. Now creates MICs based on an input Material, instead of new Material. Added ability to emit a flattened debug mesh, and print debug info.
MergeActors:
- Expose above improvements to IApproximateActors
