Provide CLI-Parameters via Application.OnLaunched

[TopperDEL]

I was stumbling across the problem, that CLI-parameters (or the one defined within the launchsettings.json) do not get reported via the OnLaunched LaunchActivatedEventArgs.Argument-Property. Couldn't this be streamlined?

Otherwise I have to check args.Arguments and Environment.GetCommandLineArgs() for possible provided arguments. This is espacially necessary together with Uno Plattoform, as WASM provides the parameters via args.Argument but WinUI does not.
