[ENG-9959](https://linear.app/comm/issue/ENG-9959/improve-scanning-qr-code-flow). 1. Implement `QRAuthNavigator`, other screen in QR Auth flow are going to be part of this. 2. Moved existing `SecondaryDeviceQRCodeScanner` to be part of `QRAuthNavigator`. `screenOptions` in `QRAuthNavigator` are the same as in `RegistrationComponent` as we want those two flows to look consistent. In [ENG-9968](https://linear.app/comm/issue/ENG-9968/final-testing-task) there is example of how this looks like.
