[gtk+/client-side-windows: 151/284] Don't use drawable_get, release_context in _gdk_windowing_create_cairo_surface

    Don't use drawable_get,release_context in _gdk_windowing_create_cairo_surface
    
    This fixes a mismatch in save/release gstate for the CGContext. If
    this function is ever used for pixmaps, we need to add support for
    that, probably will have to do so soon.
