I think we need to move it to the if(ICEBERG_BUILD_BUNDLE) block below since it depends on Avro and Parquet libraries.

IMHO, we don't need to add test cases for a pure interface classes. We can keep it for now and then remove all these cases once we have implemented DataWriter.

The test depends on Avro and Parquet libraries, so it should be built within the ICEBERG_BUILD_BUNDLE conditional block.
