Add the secondary sub to internet dialog

For feature auto data switch:  The feature only
applies to non-DDS. If enabled, we automatically switch to the non-DDS for data traffic when it has better availability than the DDS.

After the change(UI required by b/247880971), when the secondary SIM is being used, it will show up
on the internet dialog and be highlighted. Taping on the gear icon will
bring the user to the secondary SIM setting page.
