benchmark: remove offset audit workloads

The offset audit added page-backed style-set and grapheme-map workloads
to measure candidate changes. They are useful for investigation but
broaden the benchmark CLI beyond the final production changes.

Remove the workload implementations and registrations for now.
Performance results remain in the individual commit messages, so the
harnesses can be restored later if needed.
