* Generic Multi Function Call ability added to extensible nodes
* Code gen improvements, including allowing for more manually codewritten extension of codegen facilities
* CVAR to disable automatic update of deprecated node
* Fixed variable sorting error that can apply to parser/runtime added variables
* Made Edit/SerializeContext ClassBuilder public, as it was needlessly private
* Fixed dangerous Datum::GetValueAddress(), it now checks for an empty storage AZSTd::any, as does Datum::Empty()
The following was changed:
- The remapper in AZ::IdUtils now has an additional argument to tell it what to do when it encounters the same source entity id. The original behavior of ignoring the new entity id and returning the first occurrence is the default. The alternative behavior is to store the last known entity id and return that instead.
- Split the optional arguments for SpawnAllEntities and SpawnEntities.
- SpawnEntities now has an option to continue with the entity mapping from a previous spawn call or to start with a fresh mapping. The latter is the default as the former will come at a performance cost since the mapping table has to be reconstructed.
- Entities spawned using SpawnEntities and ReloadEntities now also get the correct entity mapping applied.
- Added several new unit tests to cover most of the new functionality.
- Fixed some places where the older API version was still called.
Several UI property handlers were incorrectly using the autoDelete feature by calling UnregisterPropertyType and deleting the pointer themselves, which caused double-delete crashes on application shutdown. PropertyManagerComponent now gracefully handles that condition but also explicitly asserts explaining how the code should be changed, and the "known offenders" have been fixed up to use autoDelete correctly.
