client: Disable threaded GL on desktop NVIDIA

Otherwise QtQuick windows freeze when resized. In order to still use threaded rendering on embedded platforms where resizing is not required we check if XDG_CURRENT_DESKTOP which should be set by desktop environments. Task-number: QTBUG-95817 Pick-to: 6.7 6.6 6.6.2 Change-Id: Ic2348c3169e0ade8c5463e3d7c7a1c45037a89a7 Reviewed-by: Eskil Abrahamsen Blomfeldt <[email protected]> Reviewed-by: David Edmundson <[email protected]>
