MSIX packaging for arbitrary .NET project types

[daniel-lerch]

Is your feature request related to a problem? Please describe.

The .NET SDK supports streamlined MSIX publishing for WinUI 3 and MAUI projects. For other project types one can use an application packaging project. Packaging projects are cumbersome to use, more complicated to use than dotnet in CI pipeline and cannot pass MSBuild properties to child projects easily.

Describe the solution you'd like

I would like to have MSIX packaging tools for arbitrary .NET project types including Avalonia, WPF, WinForms, Console. It should be compatible with other features like single file executable, trimming and Native AOT.

Additional context

Given an app manifest and a Windows SDK installed, it should be quite easy to create an MSIX package from publish output files (PowerShell example).
