### Rationale for this change Users can define any extension data type. So we may encounter an unknown extension type. We can't use `GArrowExtensionDataType` for an unknown extension data type because `GArrowExtensionDataType` is an abstract class. ### What changes are included in this PR? This adds `GArrowUnknownExtensionDataType` and uses it for all unknown extension data types. ### Are these changes tested? Yes. ### Are there any user-facing changes? Yes. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
