StudioWelcome: Disable welcome page if inactiveqds/v3.3.0qds-3.3
On Windows 11 a side effect of having the welcome page active if up to 10% CPU load (one core) in the GUI thread if the user interacts with the GUI. If idle QDS takes 0%, but just clicking at menus can take up to 10% CPU, if the welcome page is active. See QTBUG-102549 and QDS-6750 for profiling data. This seems to be related to accessibility.
