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

- UWorldSubsystem::DoesSupportWorldType still doesn't support EWorldType::Inactive so behavior remains unchanged
- WorldPartitionCookPackageSplitter now initializes the world if it isn't already so that UDataLayerSubsystem is initialized at cook time
- Remove remaining code path where same world could be reused if it was initialized as inactive (Opening unsaved new level in content browser will now require saving first)

Added various test cases to PropertyEditorTestObject.

The mecanism to select something wihtout emiting a notification was clearing the existing pending notifications and it wasn't interacting properly with the old bacth notification system.
Also fixed a batch selection notification issue when unselecting all the selected actors from the scene outliner.

- Added IStreamingGenerationErrorHandler interface to handle world partition streaming generation errors.
- Implemented FStreamingGenerationLogErrorHandler error handler that logs errors to the console.
- Implemented FStreamingGenerationMapCheckErrorHandler error handle that logs errors to the map check window.
- Moved all map checks code from runtime hash to streaming generation code using new interface.

### ObjectVersion
- Add a new version enum EUnrealEngineObjectUE5Version.
-- This version number starts at 1000 which leaves more than enough for for EUnrealEngineObjectUEVersion to be expanded
- Even though very few changes (if any at all) to EUnrealEngineObjectUE4Version are expected there is a static assert to make sure that EUnrealEngineObjectUEVersion::AUTOMATIC_VERSION never overtakes EUnrealEngineObjectUE5Version::INITIAL_VERSION.
- Add a struct FPackageFileVersion that wraps around the version numbers and is used to store them instead of raw int32 values which was done before. This should make it easier to add new version numbers in the future if we desire (although this will cause problems in places that serialize the struct directly)
### FPackageFileSummary
- Adding a new entry to CurrentLegacyFileVersion at value -8 which shows the UE5 version being added. This lets us make the changes without needing to submit anything to UE4 Main.
- When loading a package that does not have a UE5 version, it will remain at 0.
- Added ::IsFileVersionTooOld and ::IsFileVersionTooNew to replace hardcoded tests in the code base for version validity. This will make it easier to make changes in the future.
- A few months ago most of the accessors of the version number were deprecated in favour of a version that did not contain the Engine number (ie UE4Ver -> UEVer in Archive) but to work with these changes the renamed methods now will return or accept the version as FPackageFileVersion rather than int32. The old UE4 methods will remain deprecated and direct licensees to use the new methods.
### Archive
- Now stores the version as a FPackageFileVersion rather than int32
### LinkerLoad
- Reports the larger version number if we detect a higher version number than we support. Note that this could cause an issue if the UE4 version is ever raised but helps keep the code simple.
### AssetData
- Need to add a new version here to manage existing data that only has the UE4 version
### EditorDomain
- We do not need to version the format, we can just invalidate existing editor domain entries via EditorDomainVersion
### EditorServer
- When reporting that a package is too old we report the UE4 version as that is the only version that can be older than VER_UE4_OLDEST_LOADABLE_PACKAGE
- When reporting that a package is too new it can be either the UE4 or the UE5 version so we print them together "UE4Ver|UE5Ver"
### ContentCommandlets
- The min and max resave versions have been kept as a single value, you will not be able to resave against different UE4 and UE5 versions at the same time. It doesn't seem like a useful feature and would greatly increase the complexity of the code.
- We will also only report the file version as a single value.
### ManifestUObject
- This class was setting an older obsolete version on purpose to try and maintain compatibility with older clients so we need to provide a way to create an older UE4 only version that will leave the UE5 version as unset.
### NetworkPlatformFile
- I was unable to test the code path in FNetworkPlatformFile::ProcessServerCachedFilesResponse as I am unsure how to run the game in a mode that will actually use it.
- When reading an older "CookedVersion.txt" that was saved with a single version, the reads will fail and this will count as a version change in the code so that all of the existing files will be deleted. The existing code would not give the user a log message when this happens and given the very small time window where this might happen caused by this change I have opted to leave this alone and not add any additional logging.
- If we do detect a version mismatch we will still only log the version number as a single version.
### CookOnTheFlyServer
- We now add each version number to the IniVersionMap rather than merge the version and license version as a key/value pair. This allows us to a) use both the UE4 and UE5 version numbers b) we now log a warning that the version values don't match when it is changed, previously since it was a key value we would log a warning about an additional setting instead.
-- I also added "vs" to the log message when values are mismatched to make the space between the two values being printed clearer.
