Autoenabling gesture mode only is the device is unmanaged

> Adding a protected broadcast to enable gesture mode

If the device is not managed, gesture mode will be wnabled once setup-wizard
finishes. Otherwise, it will wait for a protected broadcast from the device/profile
owner app which can switch the device to gesture mode.
