Implement Launcher::LaunchUriForResultsAsync for desktop apps #1938

Related to #1034, #1157.

In UWP apps, you can use Launcher::LaunchUriForResultsAsync to launch another app through protocol activation and make its UI show up in a modal dialog relative to the current CoreWindow. However, it can't be used with Desktop apps (other Launcher methods seem to work just fine).

It works for Win32 apps too, as CoreWindow is only for UWP apps you must use the IInitializeWithWindow interface, see https://devblogs.microsoft.com/oldnewthing/20190412-00/?p=102413

I'm trying this myself right now. Yes, you need to IInitializeWithWindow trick. My sample is packaged Win32 WinUI3 -> packaged Win32 WinUI3. The target app implements the x-launch-results protocol and correctly gets launched when doing Start > Run x-launch-results:moo?prompt=kittens ... The LaunchUriForResults, however, does not work - the Launch returns immediately with Success but no Result property.

Digging into this on my own now, stay tuned.
