Previously this was emulated somewhat by storing the paths as FStrings but this did not result in proper references that are visible to the cook.
Notes:
* Producers/consumers of asset references moved to the new types.
* Broadcast to string enabled to allow string operations on paths.
* Broadcast from string always allowed when getting values, so that legacy usages which grabbed path as string will continue to work.
* Deprecation added to migrate old path handling (string mode).
* Serialize method added to traits because FSoftObjectPath can't be directly serialized to archive.
* Fixed some project-specific static casting to FString that coudl fail when applied to SOP/SCP attributes.

* It is limited to Arrays of basic types, or arrays of structs of basic types. Arays of arrays, arrays in structs are not supported.
* Also add a new node to get the number of entries in an attribute set
* Since we support arrays now, make Get Number of Points support multiple inputs.

* Can't repro locally and seems to be random. Add more checks to be sure to not use null pointers.
* Ran the preflight until the faulty job, failed but not on this test.
