Closes #1821

Rationale for this change

This adds the proper row-lineage fields for v3. Row-lineage is enforced for v3, so all of this is done by default.

Are these changes tested?

Tests are included. I'd like to include an integration test, but we don't currently allow writing v3 manifest files.

Are there any user-facing changes?

Adds row-lineage fields.

Thanks for adding this feature!
I think it would be great to include a E2E test with spark. I believe the feature will be available in the next java iceberg release, 1.10

@kevinjqliu happy to add that e2e test! Would you prefer I wait for the release + add the test or just file an issue? I know v3 writing is blocked on this feature.
