Remove GoogleMessage3 and GoogleMessage4 benchmarks

The dataset for these benchmarks are not distributed in upstream protobuf. Therefore they fail when running `cargo bench --workspace`.

Fixes #1005

Open question:
- Are these datasets available for download? If yes, we could add them to the repo.
