winex11.drv: Allow MWM_FUNC_MAXIMIZE when WS_MAXIMIZE is present.
Mutter refuses to maximize a window when MWM_FUNC_MAXIMIZE is not present. However,
ShowWindow(SW_MAXIMIZE) on Windows can maximize the window, even without WS_MAXIMIZEBOX.
This is similar to 688fe706.
Fix Tidy Cauldron (2708320), a Unity game, unable to maximize in some cases.
