This will be a global state to control if the next applicable launch (run on iOS/Android and simulator/device at the moment) will be run with LiveView on or off. Initially the button is toggled off, and the workflow is as followed:
1. User toggles the button on and do Run > iOS Simulator, the simulator will be run with liveview;
2. User toggles it off, do Run > Android Emulator, the emulator will be run without liveview;
3. To run the iOS simulator without liveview, user will just do Run > iOS Simulator again since now the setting is off.
