Subject: [PATCH] Fix cookie consent reappearing on desktop builds (#5780)

# Description of Changes
Fix #5779. Cookie consent persistance doesn't work on desktop (on Mac at
least, not sure about Windows) because of permission differences with
Tauri. We are allowed to store things in local storage fine, so this
switches the cookie consent module to store in local storage for
desktop, and leaves it alone for web, where it already worked correctly.
