Accessibility: Use factory function instead of plugin

This simplifies deployment and makes instantiating accessible interfaces
faster since no plugin needs to be loaded.

[ChangeLog][QtWidgets] Accessibility for widgets is now included in the
widget library instead of being a separate plugin. For static builds
this means that libqtaccessiblewidgets is no longer required.

Task-number: QTBUG-32888
