Fix Unit Test failing from uninit values in CompactionServiceInput (#13080) 

Summary:
# Summary

There was a [test failure](https://github.com/facebook/rocksdb/actions/runs/11381731053/job/31663774089?fbclid=IwZXh0bgNhZW0CMTEAAR0YJVdnkKUhN15RJQrLsvicxqzReS6y4A14VFQbWu-81XJsSsyNepXAr2c_aem_JyQqNdtpeKFSA6CjlD-pDg) from uninit value in the CompactionServiceInput

```

```

This was due to `options_file_number` value not set in the unit test. However, this value is guaranteed to be set in the normal path. It was just missing in the test path. Setting the 0 as the default value for uninitialized fields in the `CompactionServiceInput` and `CompactionServiceResult` for now.

Test Plan: Existing tests should be sufficient
