GdkWindowX11: Keep the impl window cairo surface around until destroy

Browse Source 
We used to have a weak ref to the cairo surface and it was keep
alive by the references in the normal windows, but that reference
was removed by d48adf9cee, causing
us to constantly create and destroy the surface.
