* Refactored ExportToRawMesh function to allow exporting one mesh section per component
* Implemented support for UV mappings usually provided by the landscape vertex factory in the non-Nanite case (as per the LandscapeLayerCoords material expression + others)
* For Nanite landscape materials, the relevant UV channels are :
** Texcoords0-2 : TerrainCoordMapping_XY, TerrainCoordMapping_XZ, TerrainCoordMapping_YZ (note : TerrainCoordMapping_XZ doesn't work ATM because texcoords1 seems to be a special case...)
** Texcoords3 : WeightmapUV
** Texcoords4 : LightmapUV (not implemented by ExportToRawMesh yet and not supported by Nanite meshes ATM : max 4 UV channels)
** Texcoords5 : HeightmapUV (implemented by ExportToRawMesh but not supported by Nanite meshes ATM : max 4 UV channels)
* Nanite landscape meshes now have 1 polygroup per component, with the proper landscape material instance being assigned to it
* Since Nanite meshes are capped at 64 meshes per section, Nanite landscape mesh will now fail to build on proxies sporting more than this amount of components. This is a first implementation and can be fixed later by adding as many Nanite landscape components as needed
* Implemented some missing virtual overrides on FLandscapeMaterialResource leading to landscape material instances potentially being used for non-landscape usages (hair, etc.)
* Fixed LandscapeNaniteComponent not being attached to the root component (and the mesh being exported in world space coordinates), leading to it not following when moving the actor
* Added NaniteLODIndex property in ALandscape to be able to tweak the LOD level used when generating the Nanite meshes. It's mostly a debug feature to test the LODLevel > 0 landscape mesh export and to accelerate the Nanite landscape mesh generation since you usually want Nanite to be the most defined mesh possible
* All Nanite landscape meshes will be auto-invalidated by this change

This change consists of multiple changes:
Core:
- Deprecation of ANY_PACKAGE macro. Added ANY_PACKAGE_DEPRECATED macro which can still be used for backwards compatibility purposes (only used in CoreUObject)
- Deprecation of StaticFindObjectFast* functions that take bAnyPackage parameter
- Added UStruct::GetStructPathName function that returns FTopLevelAssetPath representing the path name (package + object FName, super quick compared to UObject::GetPathName) + wrapper UClass::GetClassPathName to make it look better when used with UClasses
- Added (Static)FindFirstObject* functions that find a first object given its Name (no Outer). These functions are used in places I consider valid to do global UObject (UClass) lookups like parsing command line parameters / checking for unique object names
- Added static UClass::TryFindType function which serves a similar purpose as FindFirstObject however it's going to throw a warning (with a callstack / maybe ensure in the future?) if short class name is provided. This function is used in places that used to use short class names but now should have been converted to use path names to catch any potential regressions and or edge cases I missed.
- Added static UClass::TryConvertShortNameToPathName utility function
- Added static UClass::TryFixShortClassNameExportPath utility function
- Object text export paths will now also include class path (Texture2D'/Game/Textures/Grass.Grass' -> /Script/Engine.Texture2D'/Game/Textures/Grass.Grass')
- All places that manually generated object export paths for objects will now use FObjectPropertyBase::GetExportPath
- Added a new startup test that checks for short type names in UClass/FProperty MetaData values
AssetRegistry:
- Deprecated any member variables (FAssetData / FARFilter) or functions that use FNames to represent class names and replaced them with FTopLevelAssetPath
- Added new member variables and new function overloads that use FTopLevelAssetPath to represent class names
- This also applies to a few other modules' APIs to match AssetRegistry changes
Everything else:
- Updated code that used ANY_PACKAGE (depending on the use case) to use FindObject(nullptr, PathToObject), UClass::TryFindType (used when path name is expected, warns if it's a short name) or FindFirstObject (usually for finding types based on user input but there's been a few legitimate use cases not related to user input)
- Updated code that used AssetRegistry API to use FTopLevelAssetPaths and USomeClass::StaticClass()->GetClassPathName() instead of GetFName()
- Updated meta data and hardcoded FindObject(ANY_PACKAGE, "EEnumNameOrClassName") calls to use path names

WP Landscape HLOD - Properly stitch landscape HLODs & the actual landscape components
FLandscapeMeshProxySceneProxy now register the LOD they represent in the LandscapeRenderSystem object, causing the neighbor landscape components to morph their vertices to fill any gap.

- When enabled, folders are actual objects : modifying a folder won't affect actors (more compliant with OFPA).
- Enabled by default for World Partition and Level Instances.
- Can be enabled on regular levels (experimental feature 'Use Actor Folder Objects').
- If Level uses OFPA, ActorFolders will also be saved in their own package (but will use __ExternalObjects__ root folder).
- In a future refactoring, external actors will also be moved in the same root folder.
- Generalized saving object in an external package (different from its outer package)
- World outliner supports old folders and new actor folder objects : Levels using the actor folder objects will show a root Level node (like Level Instances).
