[native] implement screen when scanning QR code a non-primary device

Summary:
ENG-9959.

Copy is taken from ENG-9936

Styles are taken from similar register screens, and there is a chance that those will duplicate with other QR Auth screens - if so I am going to refactor this but for now I prefer to keep this like this if there are any changes needed specific to a screen.

Also, after this is done maybe worth renaming the <Registration* components to <Auth* components to avoid confusion.

In ENG-9968 there is an example of what the flow looks like.

Depends on D14105

Test Plan: Navigate to screen
