Fixes two issues with MSIXVC2 packaging in Xbox Game Package Manager:
When uploading an MSIXVC2 package via the legacy Upload a Package path, the error screen's "Go Back" button incorrectly navigated to Msixvc2UploadView instead of back to PackageUploadView where the user started.
Fix: Added UploadOriginPage property to PackageModel. Both entry points now set this before navigating to the uploading screen. Msixvc2UploadingViewModel reads it for cancel/error navigation.
When packaging with MSIXVC2 toggle, makepkg2's /updatesubval downloads SubmissionValidator.dll but it fails to load because XSAPI.dll isn't co-located.
Fix: Added CopyXsapiDllToSettingsFolder() that pre-copies xsapi.dll from the GDK bin directory before invoking makepkg2.
