Updating PeripheralConnectivityResult in enums.xml

The definition of PeripheralConnectivityResult in enums.xml needs to
match the corresponding enum in peripheral_notification_manager.h.
Currently, the enum definition in enums.xml does not include 4 recently
added values for USB-C cable notifications. This CL updates the
definition in enums.xml to match the recently updated enum in
peripheral_notification_manager.h
