Initial version of the debugger
- currently compiled by StateTreeModule and StateTreeEditorModule using WITH_STATETREE_DEBUGGER
- currently not exposed to UI by StateTree settings 'bUseDebugger'
- in this version only one instance per asset can be debugged
- using Trace services to read events generated by statetree instances.
- can connect to any traces (Editor, Client, Server) as long as the compiled statetree matches

Also removed the Mutable named functions and replaced with the constness being part of the template.

[CL 24197313 by stephen holmes in ue5-main branch]
- refactored the property binding representation, editor binding shave now more structure, and removed intermediate representation
- added functionality to resolve property paths agains a known value
- added instanced struct and object indirection types
- added editor functionality to allow to bind to further than first level of properties
- refactored editor tree traversal, allow to access values too
- simplified statetree node ui
- requires to recompile trees, bumped version

[CL 24117094 by mikko mononen in ue5-main branch]
- Added ability for tasks to request transitions
- Added buffered transition requests
- Added callback method to FStateTreeTaskBase which is called during transition triggering
- Allow FStateTreeStateLink to be added to tasks and conditions (resolved automatically during compile)

List of optimizations and changes:
* Token stream structure
* Split token stream into strong-only and a mixed (weak+strong) stream
* Split token stream into a builder and a tighter view class which reduces sizeof(UClass)
* Implemented ref-counted token stream view sharing
* Removed Class and Outer from token stream
* Allow empty token streams (enabled by removing Class/Outer) to avoid touching token stream data
* Placed ARO (AddReferencedObjects) last to reduce per object cache thrashing, improve control flow predicability and avoid reading the last EndOfPointer and EndOfStream tokens
* FPrefetchingObjectIterator that bring in Class/Outer, class' tokenstream view and the first token data ahead of time
* Decode token bitfield once and ahead of time
* Reference queues and batch processing
* Introduced bounded queues: ref arrays -> unvalidated refs -> validated (non-null / non-permanent) refs
* Split all these queues for killable vs immutable references
* Stack-living references still handled synchronously. With removal of Class/Outer (prefetched ahead of time) few instances remain outside of ARO calls.
* Outer queues hold 32 items and get flushed when full.
* AddReferencedObjects (ARO) optimizations
* Misc optimizations in many ARO implementations
* New FReferenceCollector API to queue up ARO references (AddStableReference), old sync API (HandleObjectReference) still available
* New AddPropertyReferences traversal that replaces SerializeBin and PropertyValueIterator
* 4.5x faster than PropertyValueIterator
* Uses CLASSCAST dispatch instead of virtual SerializeItem dispatch.
* Step towards new unified token stream replacement shared by class token processing, structs and ARO
* Replaced StructUtil::AddReferencedObjects with AddPropertyReferences traversal, ~8x speedup and collects more references for CitySample
* Parallelism
* Single long-running task per worker
* Improved work-stealing / load-balancing, workers can steal full blocks, ARO calls and initial references
* Queue up slow ARO calls to improve load balancing and avoid late stragglers. Motivated by certain ARO calls taking over 2ms for a few specific objects.
* Kick tasks manually to avoid ParallelFor end synchronization
* FGCObject
* Initial reference collector runs in parallel with mark phase
* New FGCObject constructor API (AddStableNativeReferencesOnly) to opt-in to initial reference collection, used by StreamableManager
* Same constructor API allows FGCObjects to defer registration until they become active (RegisterLater), reduces number of active GCObjects
* Reduced memory usage
* Allocate reached objects in scratch pages (FWorkBlock) and reuse processed blocks, instead of swapping two big TArray<UObject*> per worker
* Reduced sizeof(UClass)
* Shareable token streams
* Misc optimizations
* New API to test if an object is in the permanent object pool. Old API read two global pointers for every visited reference.
* Fixed signed integer usage in GUObjectArray lookup that led to bad codegen
* FPropertyIterator optimizations
* SerializeBin optimizations
* Other changes
* Moved many helpers into UE::GC namespace
* Replaced TFastReferenceCollector API with simplified CollectReferences call. Needed to break this API any way.
* Introduced FGCInternals to avoid forward-declaring TFastReferenceCollector and depend on the options enum in common headers
* Moved and outlined code from GarbageCollection.h / FastReferenceCollector.h to GarbageCollection.cpp
* Moved GC History and Garbage Reference Tracking into a synchronous TDebugReachabilityProcessor
* Removed PersistentGarbage flag since it wasn't used in practice
* Improved const correctness
