[Feature]: Create .appinstaller info for a package

[DrusTheAxe]

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

1. Create a .appinstaller file for a .msix package
2. Create a .appinstaller file for a .msix package AND embed in the package
3. Create Msix.AppInstaller.Data\MSIXAppInstallerData.xml in a package (and referenced images, if any)
4. Create .appinstaller file for a .msixbundle containing multiple architectures of a main package (is it even possible to create an architecture-independent .appinstaller file for a bundle?)
