[OWE] Support OWE in transition mode

Support OWE in transition mode for devices with OWE support
and devices without OWE support. Scan results will return a
new type of network for OWE in transition networks on devices
that support OWE, and Open for devices that don't support OWE.
Handle the case where Open network is manually added to a device
that supports OWE.
