- configurable severity
- separate cvar for shipping configuration
- strip sublevels from list to check if the owning world was also leaked
- optional minimal mode that searches for direct, external references to the target objects or one of their inner objects (e.g. actors in a world) for less memory overhead - uses about 225kb in one test (vs hundreds of mb)
- fix fatal logging option to log all errors before crashing
- optimize reference graph to skip leaf nodes, reduces cost from 500mb -> 335mb in one test
- only store a callstack in nodes that actually need it, reduces cost from 335mb -> 100mb in testing

otherwise an unresolve `TObjectPtr` could resolve to nullptr causing determinism issues

- Hexdump of the whole compressed shader will be dumped if small enough (which is what we're seeing mostly).

- This fix an issue where Niagara emitters being loaded from templates could end up with duplicate unique identifier as they were first being duplicated to a transient package before being moved (via UObject::Rename) to the final package. This meant we had no way to produce a unique guid for the editor bulkdata.
- This solution does mean that we are not producing stable guids between multiple runs of the editor (the above scenario occurs every time the Niagara package is loaded) but that requirement is for future features that are not yet online. We will revisit this code in 5.2 to implement a solution that does produce stable guids.

This is to faliciate validation by inspecting the header as well as allow asset patching using solely the header without export loading.
Deprecate FolderName in UPackage and replace it in PackageSummary with the PackageName
Use to replaced PackageName to generate relative path loading when detecting a package has been relocated which allows some support for asset manipulation through normal file operation

Fix for destroying ChildActorComponent sometimes fails assert in UObjectBase destructor checking for NAME_None.
Previously GIsGarbageCollecting was only set during the internal IncrementalDestroyGarbage function, and was missing for the UnhashUnreachableObjects function that is responsible for calling UObject::BeginDestroy.
This was probably a mistake when incremental GC was first introduced, and not what client code like UChildActorComponent::DestroyChildActor is expecting.
We always want BeginDestroy to the behave the same no matter if it is called from a full blocking GC (when GIsGarbageCollecting=true is already true) or from an incremental GC step.
Change type of GIsGarbageCollecting from FThreadSafeBool to a normal bool. It is only set from GT, and it should only be read from GT (it does not make sense on other threads, nothing that cares about it should run at this time).
Explicitly silence ~SObjectWidget ensure on engine shutdown since GIsGarbageCollecting is now set in this scneario too (no actual change in behaviour).
