comctl32/theme_dialog: Pass the WM_SYSCOLORCHANGE message to the original dialog procedure. 

Even though themed dialog itself doesn't need to repaint after WM_SYSCOLORCHANGE is received,
WM_SYSCOLORCHANGE should be passed to the original dialog procedure DefDlgProcW(), which can then
forward WM_SYSCOLORCHANGE to its common controls and call COMCTL32_RefreshSysColors().

Fix wrong property sheet tab background color after winecfg disables theming.
