Add thermal control interface to zone objects

When in control mode, the thermal control interface and mode property
are added to each zone object. The object path for each zone consists of
the configured object path plus the zone number.
Ex) /xyz/openbmc_project/control/thermal/0

Tested:
    After fan control is started in control mode, dbus interface exists
