Add initial preferred APN feature

In multi-sim scenarios, each sim will have its own preferred APN
setting. When ApnSettings sets/reads the preferred Apn, SUB id will
be passed to TelephonyProvider.  TelephonyProvider will update/return
the value of the key 'apn-id0' or 'apn-id1' based on the given SUB id.

Telephony: Disable PIN Toggle option if SIM is in Locked state.

When user presses cancel in PIN lock screen, card will be in
LOCKED state and hence cannot access SIM for any transactions.

So Disable PIN Toggle option in Locked State.

Telephony (MSIM): Retain the pref selection when set voice sub fails.

When set voice subscription fails due to sub not activated, the
preference selection is not reset until the Activity is resumed.
Return false for onPreferenceChange() so that UI is reset back to
original value.
Similar fix done for set priority subscription and set sms
subscriptions also.
