[WIN32SS:NTUSER] Completely update the metrics in co_IntInitializeDesktopGraphics().

This change is similar to what is done in UserChangeDisplaySettings()
    after changing screen video mode.

This allows e.g. having windows to be correctly maximized during
    2nd-stage GUI setup. To compare and reproduce during 2nd-stage GUI
    setup, open cmd.exe (Shift-F10) and from there a GUI app, e.g.
    regedit.exe, and maximize it. Observe the limits used by the window.
