UX: Split hide_profile_and_presence user option (#29632)

It splits the hide_profile_and_presence user option and the default_hide_profile_and_presence site setting for more granular control. It keeps the option to hide the profile under /u/username/preferences/interface and adds the presence toggle in the quick user menu.
