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

- Allow to load property bags with missing struct, enum, and object types
- Mark missing types with specific types so that we can report error in the UI
- Report missing types in the UI

Only the ImportText flow of changing a property actually calls PropagatePropertyChange, so we need to use SetPerObjectValues (which calls ImportText internally) rather than directly copy the struct state.

- Changed GetOrCreateFromDescs() to always ensure on errors
- Added method to migrate to another property bag instance
- Added metatag "FixedLayout" which allows to only edit values, not layout
- Changed the details customization to be allowed to embed in other customizations

The child struct properties can't inherit the sparse data flag, as FStructurePropertyNode is already directly editing a block of struct memory.
This also includes a workaround for a crash when propagating changes from a FStructurePropertyNode nested within an object, as the sparse data flag used to workaround it but that is no longer set.

- Property bags allows to create customs structs via code or UI and store them in an property bag instance
- Bags are identified by their layout, a UScriptStruct is created for each unique layout
- The instances serialize the layout, not the type, to simplify handling with old data
- Property values can be migrated between different bags

FInstancedStruct now edits a copy of the data (like FStructVariant did) to avoid issues where the detail panel would try and access invalid data. This copy is migrated back to the source whenever a property on the struct is edited, and the source is synced to the copy either every 0.1s or immediately on undo/redo or when the source is edited via its property handle.
The custom revert logic has been removed now that FInstancedStruct implements Identical correctly (as a deep-compare for a value type), and the customization now reads the meta-data from the correct property (to handle containers of FInstancedStruct) as well as handling the "HideViewOptions", "ShowTreeView", and CPF_NoClear meta-data that the standard struct picker supports.
