Refactor implementation of native and Skylark declared providers.

1) Instead of having a single class for both, split them into
   {Skylark,Native}ClassObjectConstructors
2) Allow NativeClassObjectConstructors to customize their instantiation
   logic.
3) Prepare ClassObjectConstructor.Key to be serializable.
