feat(jsii): Erase un-exported base classes instead of prohibiting those (#425)
When an exported class extends an un-exported class, merge the declarations of the un-exported base into the exported one, and replace the base class relationship with the base's own base (recursively until an exported base is found, or no further base class is declared - in which case the exported class will not have a base class at all). Declarations from the erased base class(es) will be ignored if there is another declaration with the same name and type in the exported type (or another erased base class that is closer to the exported type in the inheritance chain). Fixes #417
