Add events to Scene component

[grozdanov]

magic-script-components-lumin Scene component supports:

• onAppStart(initData), where:

initData = {
      uri: <string>, // Deep linking URI value
      isInternetConnected: <boolean>, // there is an internet connection
      isWiFiConnected: <boolean>, // WiFi Connected status
      isWiFiEnabled: <boolean>, // Wifi is enabled in settings
      isShareableApp: <boolean> // Able to replicate the scene graph on the remote device
}

• onAppPause()
• onAppResume()

magic-script-components-react-native needs to provide support for the listed events as well. Most likely initData.isShareableApp will be false until we find mechanism to replicate JSX across devices.
