WPS: Cross band overlap detection with multiple interfaces

When WPS is running simultaneously on multiple per-band radios (e.g., a
separate 2.4 GHz and 5 GHz band radios in an AP device), handle
synchronization of scan results, detect PBC session overlap, and cancel
WPS for enrollees on both interface, if the UUID of the registrars on
different bands differ.
