User-installed addons are broken on Android

Summary

User installed addons can be installed but cannot work because they are disabled by default in Private Browsing, and our patches hide the UI to change this setting (ironically, on the assumption users have no business at disabling them).

Steps to reproduce:

1. On TBB for Android version 11.5, install any of the addons listed in Settings>Addons, e.g. uBlock
2. Try to use it, e.g. by opening its Settings page

What is the current bug behavior?

Blank or non-interactive addon UI

What is the expected behavior?

Regular and interactive addon UI

Environment

Tor Browser 11.5 on Android 12 from Google Play
