JeanMichel Dignard 9d7c15b9b7 Interchange: Changed AssetImportResult to be able to hold multiple assets. ...

- FAssetImportResult is now stateful, going from InProgress to Done when all assets have been imported.
- It's possible to request the list of assets while the import is InProgress. The list will be partial.
- A callback is available to be called once the import is complete and all the results have been made available.
- For non async code paths in Datasmith. a FAssetImportResult is created, its asset is immediately added and its status is set to done.
- Added a new InterchangeEngineFwd to put forward declarations for the Interchange Engine module so that we don't have to write the namespaces all the time.
