        Web Inspector: Elements: always show all navigation bar items, but disable those that wouldn't work

        Reorder the navigation items of the Elements tab (left to right):
         - Show rulers
         - Force print media styles
         - Force Dark Appearance / Force Light Appearance
         - Show compositing borders

         - Show shadow DOM nodes
        This way, "related" (e.g. print styles and dark/light appearance both relate to CSS media)
        toggles are grouped closer together.

        Match the behavior of JavaScript breakpoints, which enable breakpoints globally when a new
        breakpoint is set or an existing breakpoint is enabled.

        This avoids the situation where setting a DOM breakpoint or a specific event listener
        breakpoint appears to not "work" because breakpoints are globally disabled. There is no
        "breakpoints disabled" banner in the Elements tab, so the user could be completely unaware
        of this, and therefore be confused as to why these breakpoints aren't being hit.
