When a system tray icon on Windows wasn't visible (hidden behind the ^
icon in the task bar) our previous implementation gave different
results on Windows 10 and Windows 11.
On Windows 10 the geometry returned the geometry of the ^ icon itself
while we returned a geometry outside of the screen geometry on Windows
11 (that was what the Windows API gave us).
We work around this problem by using version specific hacks to be able
to check for the visibility of the system tray icon itself. If the icon
is hidden we just return QRect().
[ChangeLog][Windows] The geometry of a hidden QSystemTrayIcon was
unified over different Windows versions. It will always return QRect()
now.
