Command to deduplicate command menu items (#19202)

- Deduplicate standard record command menu items by merging
single-record and multi-record delete, restore, destroy, and export
actions into shared record commands.
- Update frontend command registrations and engine component mappings to
use the new unified keys, while keeping deprecated engine keys
temporarily mapped for backward compatibility.
- Add a 1-21 upgrade command that removes legacy command menu items from
workspaces and creates the new unified standard items.
