What does this PR do?
We would like to use a different library for scene asset import yet still benefit from all offerings of the Scene API pipeline.
This PR reviews the interface between Scene API and AssImp and fixes the abstraction where it was leaking or non-existent.
It is an enabler for addition of different scene import libraries as Gems. By itself no functional changes were intended: all existing assets should be imported as before.
It removes references to AssImp specific code from the generic part of the SceneBuilder/SceneImporter.
It enhances SceneWrapperBase with additional methods that provide clear boundaries.
It refactors AssImp SDKWrapper and AssimpImportContext to be provided by AssimpImportContextProvider factory.
It uses Abstract Factory Pattern to decouple AssImp specific ImportContext from SceneImporter
It implements an ImportContextRegistry Interface for registration of additional ImportContextProviders
Note this target stabilization for convenience. Will be rebased against development after internal review
