fix: dotnet abstract classes should have proxy implementations
Abstract classes have can implementations that are not shared thorugh jsii. When trying to instantiate one for these types as a return value, the runtime crashes. This change creates proxy class types for abstract classes. These types can be instantiated, and have implementations for any methods/properties marked as abstract. Fixes aws#233
