net/mlx5: SD, make primary/secondary role determination more robust

Refactor SD group registration to use devcom event-driven role
determination to ensure SD is marked as ready only after roles are fully
assigned and the group state is consistent, making outside accessors,
which will be added in downstream patches, safe to use without races.

The devcom events:
- SD_PRIMARY_SET event: each device compares bus numbers with peers
  to determine which should be primary
- SD_SECONDARIES_SET event: secondaries register themselves with the
  elected primary device
