Option to choose front or back camera during the camera permission

[KrasnayaPloshchad]

What is the user problem or growth opportunity you want to see solved?

After #15421 the camera is now default to front one during the permission, but there are some requests to create a drop down menu to select which camera to be used during the permission, that is what you’ve made before Fenix.

How do you know that this problem exists today? Why is this important?

There are some sites requiring camera for reading QR codes, but doesn’t give permission to choose which camera to use, without this option it’s inconvenient to use them sometimes, such as https://qrcodescan.in/, https://www.qrstuff.com/scan, https://www.the-qrcode-generator.com/scan, https://8w.8thwall.app/scan/ With such sites it’s possible to reproduce this issue.

Who will benefit from it?

Anyone who needs to switch the camera in Firefox, and who is using device with more than one camera.
