Previously, a new `QtXAccessible` object was created for an `XAccessible` each time before `QAccessible::queryAccessibleInterface` was called, which is not only unnecessary but also causes various issues, e.g. it breaks walking the a11y hierarchy upwards (i.e. from children to parents), since a new object is created for the parent. This introduces `QtAccessibleRegistry` that keeps a mapping between the `XAccessible` and the associated `QObject`. That mapping is used to reuse already created objects instead of creating new ones for the same `XAccessible`. The entry for an `XAccessible` is removed again from the map in `QtAccessibleWidget::invalidate`, which gets called when the `XAccessible` gets disposed, s. `QtAccessibleEventListener::disposing`. With this in place, Orca now also nicely announces only the text of the push buttons themselves in the "Save Document?" dialog when switching between the buttons using the Tab key, rather than announcing the whole widget hierarchy every time (probably because creating a new object every time prevented Orca from recognizing that the previously selected pushbutton and the newly selected one are siblings, i.e. have the same parent object.)
