Add the NonRemovable property to the Package class

[bogdan-patraucean]

Could we add the NonRemovable property to the Package class?

I have this property available when I query the list of apps using Get-AppxPackage from Powershell.

This way we offer developers a safe way to use the PackageManager as they can ignore apps that have NonRemovable set to true. Now this is available just in Appx-Module for Powershell.

The problem is that for example in Wintoys, where users can uninstall all the apps, I have no way of ignoring the non removable packages by default. I ignore everything that's part of the SystemApps folder but this is not enough.

It would be really nice to have the flag available in the Package class as it would help developers offer a better experience in their apps.
