tdf#149816 qt a11y: Report position in screen coordinates

`QAccessibleInterface::rect()` is supposed to report the
geometry in screen coordinates [1].
`XAccessibleComponent::getLocationOnScreen` returns the
position in screen coordinates, so use that instead
of `XAccessibleComponent::getLocation`, which returns the
position relative to the parent.

With this in place, Accerciser correctly highlights
the area of the item curently selected in its treeview
of the LO a11y hierarchy.
