fix: resolve silent failures in AppX removal and PS7 DISM bugs (#4822)

* fix: resolve silent failures in AppX removal and PS7 DISM bugs

- Fixed a bug where Remove-AppxPackage failed silently in PowerShell 7 due to pipeline binding issues. We now explicitly loop through Get-AppxPackage results and pass PackageFullName directly.
- Added wildcard matching to Get-AppxPackage and Get-AppxProvisionedPackage to reliably locate packages regardless of short name vs family name variations.
- Offloaded Get-AppxProvisionedPackage and Remove-AppxProvisionedPackage execution to Windows PowerShell 5.1 (powershell.exe) to bypass PowerShell 7 DISM COM exceptions ("Class not registered") and performance hangs.
- Deduplicated AppX removal logic by calling Remove-WinUtilAPPX directly from Invoke-WPFAppxRemoval instead of copying the implementation.

* refactor(Remove-WinUtilAPPX): use script block to improve readability

* feat: enhance AppX removal process and add provisioned package removal function

* fix(tests): update AppX removal tests

This also adds tests for the new Remove-WinUtilProvisionedAPPX functionality

* Move AppX removal under Tweaks

* Address AppX removal review feedback

* Complete AppX removal error handling

* Prevent AppX cleanup confirmation prompts
