[Firefox] Fetch browser preferences/options together with the viewer preferences (bug 1862192)
Currently we *synchronously* fetch a number of browser preferences/options, from the platform code, during the viewer respectively PDF document initialization paths. This seems unnecessary, and we can re-factor the code to instead include the relevant data when fetching the regular viewer preferences.
