[Accessibility] disable accessibility for some elements in QML

[Pierre Lamot]

>This is strange, in general elements that don’t have Accessible.something set should not appear for TalkBack at all. Please try to come up with a small example that shows this behavior (it should be easy enough to just create a simple qml file) and file a bug at bugreports.qt-project.org with GUI: Accessibility as component.

I opened this bug [1], but it seems to be rather related to ministro than Accessibility itself:

>iOS accessibility support is in the dev branch - which is Qt 5.4. Feedback is much appreciated there, but of course it required building Qt. I still need to implement rotation (currently everything works after rotating the device but visually VoiceOver will show the focus rectangle as it it wasn’t rotated).

I'm about to test it. I'll give feedbacks if I find any problems.
