Add hidden SystemApi for two setup wizard actions

ACTION_UPGRADE_SETUP exists as an SdkConstant and is now additionally
tagged as a SystemApi. ACTION_DEVICE_INITIALIZATION_WIZARD is added
as a deprecated SystemApi to appease CTS requirements. Both APIs are
hidden.

Test: cts-tradefed run cts-dev -m CtsSignatureTestCases \
        -t android.signature.cts.IntentTest#shouldNotFindUnexpectedIntents
