cocoa_common: avoid window creation with VOFLAG_HIDDEN
This takes an approach similar to the wayland OpenGL backend. VOFLAG_HIDDEN flag semantics doesn't mean "hide the window" but is simply ever used only to do detection of available OpenGL extensions. On OSX it's possibile to accomplish this task just by creating the OpenGL context without attaching it to a drawable.
