api: new NetworkRejection property

When a modem is not able to register to the network, MBIM and QMI indications
related to registration reports network rejection cause codes if request is
rejected by the network. This information is currently logged in the ModemManager
but not exposed outside of ModemManager.
These are the changes to define interface to expose network reject cause codes
over d-bus to the above layers which could be used by above layers to present
this information in a user friendly way.
