Documentation: state: recommend a partition type GUID for state GPT partitions
The partition type GUID was generated randomly. Having a defined GUID should reduce the risk of collisions in the future. A dedicated GUID could also allow us to implement a fallback in case no state backend property is defined. This could then look for a GPT partition with this partition type GUID and use that as the backend. dt-utils could do the same in userspace. This would be similar to [1].
