The equals and toString translations are open regardless of their parent classes

[vinivendra]

The translations for == and description are done manually and always include the open modifier. This is a problem when the enveloping class is marked as final, which causes Kotlin to raise a warning (since these methods can't be overridden anyway).

It would be better to set the isOpen property instead of adding the open keyword manually so it could be treated correctly. In this case, it's important to check if the transpilation pass that handles open/final comes after the one that translates == and description.
