Add Attestation IDs State to DeviceInfo

We will use the 'Attestation IDs State' field in DeviceInfo to
determine whether a device is still provisionable or not. Once a
production device has left the factory, certain attestated device ids
should be fixed, and 'Attestation IDs State' should reflect this
by reporting "locked".

Remove stale, duplicated DeviceInfo description from ProtectedData.aidl
