[epiphany] Add enable_gsb option to active safe browising feature

[Michael Catanzaro <mcatanzaro src gnome org>]

commit fda3de9f89c63aa530a34ffa7365439a8bfd369e
Author: Jan-Michael Brummer <jan brummer tabos org>
Date:   Tue Sep 29 17:51:04 2020 +0200

    Add enable_gsb option to active safe browising feature
    
    In case we cannot provide a gsb api key, we should disable the service entirely and
    hide the config option in preferences window.
