cmd, disk: convert CONFIG_PARTITION_UUIDS, CMD_PART and CMD_GPT

We convert CONFIG_PARTITION_UUIDS to Kconfig first.  But in order to cleanly
update all of the config files we must also update CMD_PART and CMD_GPT to also
be in Kconfig in order to avoid complex logic elsewhere to update all of the
config files.
