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.

On a large test asset, this shaved off ~20 seconds on a ~1m50sec merge operation.

HLOD meshes were sometime referencing MaterialInstanceDynamic, that aren't assets (!RF_Standalone)
* MIDs are usually outered to the components they are assigned to
* Duplicate MIDs and outer them to the generated HLOD UStaticMesh

WP HLOD - Add Landscape support
Changes to support WP landscape material capture
* Moved IsValidBaseMaterial() from MeshMergeUtilities to MaterialUtilities
* Moved CreateProxyMaterialInstance() from MeshMergeUtilities to MaterialUtilities
* Added FCreateTexture2DParameters::bVirtualTexture
* Added FMaterialUtilities::ExportLandscapeMaterial() which doesn't need a list of primitives to hide (will only render the landscape component primitives)
* Added VT primming to ensure the captured textures have the expected resolution

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.

Fixed test failure - ActorMerging_SingleLODMaterialBaking
Corrected bad conversion from EMaterialProperty to EFlattenMaterialProperties using array indexing... now using a map.
Fixed slight delta in ground truth images as the floor pattern moved a bit (irrelevant to the actor merging test)

The scheme solves issues where meshes would no longer align properly after converting them to Nanite. It also solves the precision issues in clusters with triangles of non-uniform size.
By default the precision is heuristically selected by Nanite, but the user also has the ability to override with an explicit precision to solve issues or optimize for disk size.
Clusters store the coordinate components using the minimal number of bits required to span the range of values in the cluster.
Apart from fixing issues, the default quality seems no worse than before and is typically ~5-10% smaller than before.
Added Position Precision to the top left of Mesh viewer along with the other mesh stats.
Added Position Precision dropdown to Nanite import settings.
Added debug mode "r.nanite.visualize PositionBits" that shows the vertex position bit sizes for clusters.
New quantization code now updates float positions and cluster bounds to reflect the quantized coordinates.

- Preserve guid during save if static mesh bulkdata content hasn't changed to avoid triggering unnecessary rebuilds
- Make sure the next HLOD generation is going to use the HashAsGuid feature to avoid recompiling staticmesh that are generated if they are exactly the same as before
- 31m10s to 14m15s to cook P_Construct_WP with a warmed-up DDC

* Moved default flatten material to config
