Include ServiceUI.exe in source and remove MDT dependency

[Romanitho]

ServiceUI.exe is now added directly to the repository, eliminating the need to download and install Microsoft Deployment Toolkit (MDT), which has been decommissioned by Microsoft. The build workflow is updated to reflect this change, simplifying the build process and reducing external dependencies.
