[PATCH v9 3/7] block: add block layer APIs resembling Linux ZonedBlockDevice ioctls

Add a new zoned_host_device BlockDriver. The zoned_host_device option accepts only zoned host block devices. By adding zone management operations in this new BlockDriver, users can use the new block layer APIs including Report Zone and four zone management operations (open, close, finish, reset).
