libmm-glib,3gpp: make MMModem3gppNetwork a boxed type

So that bindings know how to free the list of structs.

This commit ends up triggering an API break in the bindings generated
via GObject introspection, because the methods to access the items of
a MMModem3gppNetwork are no longer treated as Modem3gpp class methods.

E.g. instead of:
  ModemManager.Modem3gpp.network_get_operator_code(network)
We should now do:
  network.get_operator_code()

There is no API break in libmm-glib.
