I'm still confused about where this would be used besides in the user menu. Most
menu related constants live in ui/views/controls/menu/menu_config.h

I'd suggest moving this to the profile chooser view except I think the better
idea is to use a shared constant that already exists, once again to ensure
consistency.

Sorry, let me be more clear: I don't know exactly what menus will use this
margin value, but I was making an assumption that this parameter would be used
more commonly in the future when different Chrome components are converted to
standardized material design styles. But yes this was just my assumption. 
I added in this parameter because I couldn't find anything existing to use.
However, it does make sense to just move it to profile chooser view for now.
Done that, let me know if this works.
