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

[CL 20448496 by robert manuszewski in ue5-main branch]
- Changed FStateTreeHandle to FStateTreeStateHandle, used only for indexing states
- Added uint16 and uin8 index types, which can represent invalid index (aka INDEX_NONE)
- Changed indices that can be optional to the index types above
- Added validation and error loggic when index types overflow during compile
- Removed 2 indirections (in common case) and halved the memory usage of property copies

- Commented and cleaned up the members of UStateTree a bit
- Changed StateTree Node storage to FInstancedStructArray (contiguous memory)
- Changed StateTree SharedData to FInstancedStructArray
- Changed StateTree instance data to use FInstancedStructArray
- StateTree statistics shows estimated mem usage per state and max for tree (heaviest linked chain)
- Added explicit bLinked state for UStateTree
- Cleaned up UStateTree::ResetCompiled()/ResetLinked()
- Changed StateTree execution context to allocate task instance data on Start() and EnterState()
- StateTree tick uses execution order counters to access the instance data instead of compile time specific index

- Separated condition instance data into a shared instance data (mutable but no persistent state)
- Made BP TestCondition() const, conditions should not hold state
- Added macro to define runtime data POD for faster init
- Added custom serialization version for UStateTree, older assets need recompile
- Updated memory reporting to be a bit more accurate, separated shared and unique data

+ Added StateTree parameters usable for data bindings and that could be overriden on context initialization by a StateTreeReference
+ Added StateTreeReference struct to hold a reference to a StateTree asset along with a list of values to parameterized the tree.
+ Added named external data items that are defined bt the Schema and for which values must be provided at runtime through the execution context.
+ Added delegate OnPostCompile after successful compilation. The StateTreeReference listens to it to validate its parameters
+ EditorData now contains its own version of the schema and parameters. On successful compilation they are copied over the StateTree own properties.
