Technically the ability to read the manifest information from an installer would be easily implemented as the bundle can be read as zip and the manifest file could be extracted.
However importing System.IO.Compression collides with .NET 8.

Sorry, Next was a temporary branch, this PR was not closed intentionally. @mjr4077au will be in touch!

After discussion with @mjr4077au this will require #1925.
Most of the code will also be ported to PS where applicable

The commit I just pushed already implements #1925, without full wiring in the toolkit yet.
The structure of inheritance is the following:

                       | -> InstalledArpApplication -> InstalledMsiApplication
InstalledApplication - |
                       | -> InstalledAppxApplication

I also dropped everything except the GetPackageFamilyName function from c# to powershell.

Nearly all logic is now packed into the new Get-ADTPackageManifest function that can read package info from an installer (like we do with MSI) or any other valid manifest file.

Sorry @mjr4077au, I had to force push because most of the changes you applied were not relevant anymore. The ones that still were I tried to apply where applicable.
