Native: add KotlinThrowable.asError() to the generated Obj-C framework

Browse Source 
This method can be useful when overriding a throwing Kotlin method in
Swift or Obj-C. In this case, a user can call asError to wrap Kotlin exception
to (NS)Error and then throw it to Kotlin, which will unwrap it back.
