tdf#117173: qt a11y: Forward changes to SHOWING state
While Qt doesn't have an equivalent state for the SHOWING
state used in LibreOffice and in IAccessible2, it has
separate `QAccessible::ObjectHide` and `QAccessible::ObjectShow`
event types used to indicate that an object changed state
to being (no longer) displayed, so use those.
In fact, Qt's `AtspiAdaptor` handles those by mapping them to
state change events for the AT-SPI "showing" state again. [1]
