feat: Implement per-user Appx package detection and removal for Sysprep automation

- Added logic to check for per-user Appx packages that are not provisioned for all users, which could block the Sysprep process. - Introduced a hash set to store provisioned package families and collect current user Appx packages while excluding frameworks and non-removable packages. - Implemented removal of non-provisioned Appx packages with error handling and re-checking to ensure all blockers are resolved before proceeding with Sysprep.
