[Settings] Hide subscriptions not existed within device

For non-active subscriptions, the one inserted in slot
but turned off need to be visible to the user. However,
the one un-plugged need to be invisble.

Since SubscriptionUtil#getSelectableSubscriptionInfoList() didn't cover all the cases required. Create this one to fit into the criteria required here.
