[Deps]Re-evaluate workarounds after the upgrade to WASDK 1.4

[jaimecbernardo]

Description of the new feature / enhancement

The code contains quite some workarounds due to missing features in previous versions of Windows App SDK.
After #28310 (comment), the workarounds should be evaluated for removal.

Scenario when this would be used?

Code simplification.

Supporting information

No response

That particular workaround mentioned still needs to be there, as AFAIK the Windows App SDK can't automatically handle title bar text foreground (most likely due to the need to support multiple UI frameworks like WPF)

@dongle-the-gadget You mean this? https://learn.microsoft.com/windows/apps/develop/title-bar?tabs=wasdk#dim-the-title-bar-when-the-window-is-inactive

[dongle-the-gadget]

Yeah.

Maybe the "immersive dark mode" workaround could be deleted? I didn't notice it on my own app using 1.4.
