Repair-WinGetPackageManager improvements

[msftrubengu]

This PR address #3374

Change

• Make Repair-WinGetPackageManager repair known issues until its fixed or there's a non fixable state.
• Adds support for installing Microsoft.UI.Xaml.2.7 package from their GitHub release.
• Adds new parameter switch -AllUsers to Repair-WinGetPackageManager. If this is on, repair uses Add-AppxProvisionedPackage instead of Add-AppxPackage.
• Adds new integrity category to detect winget.exe failures due to missing license. To fix it Repair-WinGetPackageManager -AllUsers must be executed in admin mode.
• Fix adding preprocessor macros for net48. This cause Repair-WinGetPackageManager to always fail for Windows PowerShell.
• There's a breaking change in Repair-WinGetPackageManager. It will now throw if there's an issue repairing. Good thing this is a "prerelease" module 🗡️

Validation

Test locally on machines where Microsoft.UI.Xaml.2.7 was not preinstalled and on Windows Server 2022.
