List the IOMMU group members before adding a GPU to a VM and keep the NVENC patch state

- Add GPU to VM lists the devices from other slots that share the IOMMU group of the selected GPU before the summary
- The NVIDIA installer keeps the patched flag of the installed driver while its version is unchanged
- New messages translated into all languages
