- 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

- Changed StateTree execution context to allocate task instance data on Start() and EnterState()

- 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

[CL 20056497 by mikko mononen in ue5-main branch]
- 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

- The 'TargetProperty' pointer was utilized before it was verified against nullpt
- The modification of the 'TreeDescIndex' variable is unsequenced relative to another operation on the same variable. This may lead to undefined behavior.

+ 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.

- connect GetWorld() of FStateTreeExecutionContext explicitly to the owner
- take MassSignalSubsystem as parameter to FMassStateTreeExecutionContext directly
- separated DataViewIndex (what others see) and InstanceIndex/bInstanceIsObject (where the pointert comes from) on StateTree items
