winecfg: Use OpenThemeDataForDpi() to create a theme handle not associated to a window.

If a window is not passed to OpenThemeData(), OpenThemeData() assumes the DPI is 96 according to
tests. And GetThemePartSize() should select theme parts according to the DPI stored in theme
handles rather than using GDI device contexts. Thus, OpenThemeDataForDpi() should be used in place
of OpenThemeData() when DPI is not 96 and theme handles shouldn't be associated with a window.
