The bug was reported that copy and paste did not work with the material component.
Copy and paste to take the worked fine.
All of the material assignments/overrides get mapped using the LOD and asset ID of materials provided with the model.
The asset IDs of materials exported by atom builders, using the scene API, are the combination of the same UUID as the model asset ID and the unique sub ID that is now hashed from the material name provided by the DCC tool.
If we map material assignments using the entire asset ID that was generated in the model builder then the mapping will only work with that specific model.
This change updates the material assignment ID equality operators and hash function to only use the sub ID portion of the asset ID.
As long as the sub IDs are generated consistently the material assignment mappings will be portable to models with the same material names.
Also moved material assignment structures to atom common features static library so this was to be moved to cpp files
