power-restore: one-time support

The one_time PowerRestorePolicy property was introduced so system owners
could utilize the feature for one time type scenarios without rewriting
all of the logic on their own.

IBM wishes to utilize the one_time power restore policy to cause an
automatic power on after an in-band firmware update.

The one_time setting is defined by default within meta-phosphor here:
https://gerrit.openbmc-project.xyz/c/openbmc/openbmc/+/40948

Testing:
- Set one time and verify it's the one used and then reset to default
busctl set-property xyz.openbmc_project.Settings /xyz/openbmc_project/control/host0/power_restore_policy/one_time xyz.openbmc_project.Control.Power.RestorePolicy PowerRestorePolicy s xyz.openbmc_project.Control.Power.RestorePolicy.Policy.AlwaysOff

busctl get-property xyz.openbmc_project.Settings /xyz/openbmc_project/control/host0/power_restore_policy/one_time xyz.openbmc_project.Control.Power.RestorePolicy PowerRestorePolicy
s "xyz.openbmc_project.Control.Power.RestorePolicy.Policy.AlwaysOff"

- Verify when one time setting is at default it is ignored
