macOS: Clear NSOpenGLContex's drawable when using offscreen surfaces
Otherwise the user might accidentally render to the previously active
window, if not explicitly using an FBO.
This will have an performance impact if doing makeCurrent on a real
window and an offscreen window back and forth with the same context,
but that's not really a common or recommended use of QOffscreenSurface,
as you can create FBOs with a normal window current as well. The use
case of QOffscreenSurface is when a real window is not available.
