Scaffolding: Interleaved Table Annotations Not Added

If I scaffold from a Spanner database with interleaved tables there are no calls to [InterleaveInParent ](https://github.com/googleapis/dotnet-spanner-entity-framework/blob/main/Google.Cloud.EntityFrameworkCore.Spanner/Extensions/InterleaveInParentExtension.cs) to indicate this in the generated code. Could this be added to the scaffolded code? Thanks!
