GpuSurfacelessBrowserCompositorOutputSurfaceMac ? (lol)

I was contemplating this -- I've changed it to GpuOutputSurfaceMac instead :D

This way it matches SoftwareOutputDeviceMac, too.

+ public:
+  GpuBrowserCompositorOutputSurfaceMac(
+      scoped_refptr<ContextProviderCommandBuffer> context,
+      gpu::SurfaceHandle surface_handle,

This is from BrowserCompositorOutputSurface, not cc::OutputSurface.

Oops! Moved.
