Add ScanResultInfo object in ProvisioningConfiguration parcel.

Since wifi.ScanResult doesn't implement specific equals() yet, for
comparing the ProvisioningConfiguration object better, this change
encapuslates ScanResult#SSID and ScanResult#InformationElement member
into a new class: ScanResultInfo inside ProvisioningConfiguration.

Adding ScanResultInfo object in ProvisioningConfiguration parcelable is
to check the InformationElement filed when starting IpClient and detect
whether or not the specific OUI is included in the IEs.
