- 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

- Deprecated per state evaluators and moved them to global to the tree
- Tick evals once per Tick()
- Updated editor node customizations to work on UStateTreeEditorData
- Added separate detail customization for UStateTreeEditorData

[CL 20221385 by mikko mononen in ue5-main branch]
- 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 specific "subtree" states which can be linked to via a "linked" state
- Subtrees can only bind data back to the their root state (or tree "global" data)
- Added property bag based parameters to subtree and linked states
- Update (transient) property bag structs before resolving property paths
- Linked states reflect their parameters from the state they link to
- Added property binding to and from parameters
- Relaxed the property binding to fail if the source data is not available
- Allow enter conditions to bind to tasks, and fail the expression if trying to access unaccessible data
- Added icon for linked and subtree states
- Added source type for all binding source structs
- Added UStateTreeEditorData::VisitHierarchy to simplify iterating over all states

+ 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.

- fixed external requirements set by StateTreeBrainComponent to find more specific actor classes first before defaulting on AActor
- added missing supported type FMassSharedFragment for MassStateTreeSchema
- moved StateTreeLinker to it own file and handle its potential failures
