[PATCH 2/8] wined3d: Override WM_NCCALCSIZE for fullscreen windows.

[Rémi Bernon]

This still passes the message to the application window proc, but then
overrides the result if the window is fullscreen.

Some games restore window style after D3D has changed the window state
to fullscreen. Overriding this message will make sure the client area
always covers the full screen, regardless of window styles.
