winemac.drv: Set view.WantsBestResolutionOpenGLSurface.

This used to default to false before Catalina, and it still does so when
the application is built with XCode 10 or earlier. When building with
XCode 11 or later Catalina and newer will create a high DPI GL view even
if the window is low dpi. Because we don't adjust glViewport parameters
(and glDrawPixels, etc) we render only to the lower left quadrant.
