Keep toplevel windows in the top left corner of the screen
We can't know the actual position of a window on the screen. This causes
an issue when Widgets try to position a popup/menu absolutely and keep
it on the screen when the screen geometry doesn't include (0,0).
Instead report their positions always as the top left corner of
the screen that they are on.
This new behavior can be disabled for qt-shell or via an environment
variable by users that rely on the old behavior.
Fixes: QTBUG-85297
