Add NSStatusItemSpacing and NSStatusItemSelectionPadding

Add NSStatusItemSpacing and NSStatusItemSelectionPadding to NSGlobalDomain options.

These options control the spacing between and padding inside status icons in the menu bar. With these options it's possible to squeeze more items on to menu bar, something that's especially useful on machines with a notch!
