Allow to disable use of NSGLView

Browse Source 
On recent Mac systems (Catalina) OpenGL is slower compared to
directly using GTK's NSView. Furthermore when compiled on
Catalina, and running on a system with a Retina screen, the initial
size of the canvas may be wrong:

   libs/gtkmm2ext/nsglview.mm:175:1: warning: method possibly
   missing a [super reshape] call [-Wobjc-missing-super-calls]

This is not an issue when running versions compiled on older systems.
