Allow users to disable the QR code generator feature

[Tonev]

Description

The feature is most likely useful for a lot of users but at the same time there is another big group of users that doesn't use, or simply doesn't need the feature in their daily browsing. An option to disable the feature will allow users to keep their browser's UI cleaner and will provide a way to disable a feature they don't need at the time.

Steps to Reproduce

1. Navigate to any website (e.g. brave.com).
2. Click inside the address bar.
3. An action icon shows up in the address bar. When clicked a bubble with QR code shows up.

Actual result:

There is no way to disable the feature as of the moment.

Expected result:

Hopefully an option that allows users to enable/disable the feature whenever they like.

Reproduces how often:

Easily
