cmd: gpt: Preserve type GUID if enabled
If CONFIG_PARTITION_TYPE_GUID is enabled, the type GUID will be preserved when writing out the partition string. It was already respected when writing out partitions; this ensures that if you capture the current partition layout and write it back (such as when renaming), the type GUIDs are preserved.
