Add way to specify MSIX details such as Package Family Name for AppsAndFeatures Entries

[Trenly]

Description of the new feature / enhancement

I ran into an oddity with the Microsoft Windows App SDK Runtime where the exe installer is just a wrapper for several MSIX packages. It would be nice if the details of the MSIX package, such as the PackageFamilyName, could be specified in the apps and features entries
