GSignals for bearers addition/removal

We have the "Bearers" property in the Modem interface:
https://www.freedesktop.org/software/ModemManager/doc/latest/ModemManager/gdbus-org.freedesktop.ModemManager1.Modem.html#gdbus-property-org-freedesktop-ModemManager1-Modem.Bearers

If you're using raw processing of DBus, you'll need to listen for
org.freedesktop.DBus.Properties.PropertiesChanged signals emitted, and
monitor for the "Bearers" property being updated:

              org.freedesktop.DBus.Properties.PropertiesChanged
(STRING interface_name,

DICT<STRING,VARIANT> changed_properties,

ARRAY<STRING> invalidated_properties);

But doing all this manually is a lot of work really; libmm-glib
abstracts all this nicely and is much easier to use...
