Ability to specify if a Win32 app is dark mode aware in manifest

[jaigak]

Add an element named "darkModeAware" in the schema for app.manifest to specify if a Win32 app supports dark mode. If this value is set to true, automatically enable dark mode for common controls without the need to call APIs for that manually. This can also be used by non-GDI apps such as WinUI 3 apps to get certain system UI (eg: title bar) in dark mode when the system theme is dark.

Hi @Jaiganeshkumaran, to help us better understand your request would you be able to specify what kind of app you're intending to develop? You mentioned GDI apps, is that your intention?

I'm not intending to develop new GDI apps however this proposal could be helpful for existing GDI apps. Also many system UI in other kinds of apps such as WinUI 3 apps (eg: title bar) also require enable dark mode manually. This proposal is for automating that when dark mode is enabled in the system.

Dupe of #41?
You can achieve this effect by calling SetPreferredAppMode (which has yet to be documented)
