api,bearer: new 'ProfileId' property

To report which is the currently active profile with this bearer, if
known. If the modem doesn't support profiles, or if the bearer is
disconnected, -1 (MM_3GPP_PROFILE_ID_UNKNOWN) will be reported.

It is guaranteed that no two connected bearers will have the same
ProfileId property value.
