Add a QR Code Scanner component.

[vsnshanmuganathan]

Is your feature request related to a problem? Please describe. We use QR scanning in many places, so I would like to allow user input by scanning the QR code. Describe the solution you'd like In the Input component, please include this as a new component. Describe alternatives you've considered I tried embedding a site that has a QR scanner, but I can't get camera permission. Therefore, I need it as a component. If it's not possible, then please try to include an option to obtain camera and location permission in the Embed component.
