Add getSubscriptionId API

The old getSubId or getSubscriptionIds return multiple sub ids
per slot index, which is not possible in today's implementation
because the slot index here refers to the logical slot index,
which is also known as phone id, or the logical modem index. In
today's telephony, one logical phone can only have one
subscription at one time, so does the modem.
