Adds several improvements and additions to the gpt command processing, specifically (although not exclusively) for the purpose of supporting "ping-pong" booting when doing A/B boot partitions with u-boot itself.
In this mechanism, u-boot must boot up, and then check if the correct boot partition is active, and if not switch the GPT partition table to the other boot partition and reboot to activate the other u-boot.
In order to facilitate this, the gpt command needs to be better at preserving entry attributes when manipulating the partition table. It also learns two new commands, one which can swap the order of partitions in the table, and another that lets it change which partitions have the bootable flag.
