a11y atspi: translate coords for GetOffsetAtPoint the right way 

The coordinate type for "GetOffsetAtPoint" describes the
coordinate type of the input coordinates and
`QAccessibleTextInterface::offsetAtPoint` expects the
coordinates in screen coordinates.

Therefore, if window-relative coordinates are given,
the screen coordinates of the window need to be added
(not subtracted) to the window-relative coordinates of the point
in order to calculate the screen coordinates of the point.

Fixes: QTBUG-105281
Pick-to: 6.4 6.3 6.2
