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

Panic allows only one thread to become the panic thread. In panic mode, logs are only sent to panic-safe output devices. Each call to Panic flushes buffered logs to panic-safe output devices, and flushes panic-safe output devices.

Setters and getters are native functions called by FProperties when setting property values with *_InContainer functions.
Setters and getter function names can be manually specified with Setter = Func and Getter = Func keywords inside of UPROEPRTY macro but they will also be automatically parsed if the name is not explicitly specified if the setter or getter function name matches SetPropertyName and GetPropertyName pattern.
The latter behavior can be disabled in UHT's DefaultEngine.ini by setting AutomaticSettersAndGetters=False.
ImportText and ExportTextItem functions have been deprecated and should be replaced with *_InContainer or *_Direct variants.

2) Added new struct and class specifiers to account for settings being extracted from the engine code.
3) UHT no longer depends on pre-existing classes in the engine but will use them when it needs to create the engine instances of the classes.

The process of cooking would ensure that every BP derived from a C++ base using sparse class data would have its own sparse class data instance, as the serialization function would create an instance on save/load. This could potentially result in a lot of redundant instances that don't override any data from their archetype.
These changes allow the API for accessing sparse class data to optionally fallback to using the archetype data when possible (controlled via the EGetSparseClassDataMethod enum), though any existing code already using GetOrCreateSparseClassData (or the UHT wrapper) will continue to always create a new instance.
BPGC serialization has been updated to only save the sparse class data when it has overridden data from its archetype, and the loading code will now avoid creating the instance when no override data has been saved. This allows new code to take advantage of EGetSparseClassDataMethod by choosing to reference the archetype data instead, and the engine has also been updated to avoid calling GetOrCreateSparseClassData where possible.
Anything that requires a mutable sparse class data instance should still use GetOrCreateSparseClassData (or the UHT wrapper that doesn't take EGetSparseClassDataMethod), as otherwise you may edit data belonging to your archetype (which is why GetSparseClassData returns const data).
