Add isNewInstanceStatus to vm_payload api
This can be used by payload to determine if this the first boot of the
VM. This becomes useful since `AVmPayload_getVmInstanceSecret` is
essentially equivalent to get_or_create secrets. Payload should be able
to check if the secrets were newly created or are the old ones & this
could be used to meaningfully use the secret.
For ex, encryptedstore or other data encrypted using the VM secrets
restored via backup and restore cannot be meaningfully decrypted using
newly created secrets on the new device.
