InitializeOneOff is moved into anonymous namespace in gl_surface_mac (the only
place it was used). GetPixelFormat was dead code.

-  virtual ~GLSurfaceCGL();

-class GL_EXPORT NoOpGLSurfaceCGL : public GLSurfaceCGL {

This was moved to anonymous namespace in gl_surface_mac where it may be
instantiated for testing.
