supportedTransitions: Add in support for new prop

This new property was added [1] to allow users to define the specific
host transition operations they want to allow.

This commit starts with the default, allowing all operations. Future
commits will provide mechanisms to configure this.

Tested:
```
busctl get-property xyz.openbmc_project.State.Host
                    /xyz/openbmc_project/state/host0
                    xyz.openbmc_project.State.Host
                    AllowedHostTransitions
as 5 "xyz.openbmc_project.State.Host.Transition.On"
     "xyz.openbmc_project.State.Host.Transition.Off"
     "xyz.openbmc_project.State.Host.Transition.Reboot"
     "xyz.openbmc_project.State.Host.Transition.GracefulWarmReboot"
     "xyz.openbmc_project.State.Host.Transition.ForceWarmReboot"
```
