Compile error when using the new version of winsdk

[twinstar6980]

The version of winsdk I am using is 22621 and I encountered the error when compiling: ambigous symbol, and when I commented MENUPARTSEX in ThemeHelper, the program compiled successfully.

so, conditional preprocess should be used for MENUPARTSEX:

	// Windows 11 22H2+
#if !defined NTDDI_WIN10_NI // SDK 10.0.22621.0
	enum MENUPARTSEX
	{
		MENU_POPUPITEMKBFOCUS = 26,
		MENU_POPUPITEM_FOCUSABLE = 27
	};
#endif
