Hi,
could you please make this PR cover the "START/STOP request support" only, and undo all the cosmetics changes, that can be done in a separate PR.

- Add mass-storage “removable media” support by tracking per-LUN prevent/allow medium removal and loaded/ejected status. - Introduce an optional per-LUN callback to handle SCSI START STOP UNIT (including load/eject and power-condition fields). - Extend storage constants (media types, sense keys/codes, power conditions, prevent flags) to support the new behavior and improve readability (explicit hex values). - Initialize new per-LUN state on activation (default: medium removal allowed, medium loaded) and wire the new callback through storage initialization. - Includes minor formatting/comment cleanups and version banner updates to 6.4.6. SCSI Block Commands – 4 (SBC-4)
