Add the fully disable option for "Statistics" feature

### Issue Details

There should be an option to completely disable the 'Statistics' feature in the AdGuard browser extension. Some users may find this feature unnecessary, and for those who prioritize performance and efficiency, having the ability to turn it off entirely would be more beneficial.

Even if the performance impact is minimal or nonexistent, the mere possibility of such an effect makes offering this option the right thing to do. Additionally, it would be useful for those who prefer a cleaner UI. There have been reports in other AdGuard products where the statistics implementation caused performance issues. Adding this option would help alleviate any concerns for users seeking the lightest experience.
