[Android] Big delay while using TalkBack

QTBUG-117899 solves a lot of problems and leads to a stable layout process. But it looks like this changes lead to a lot of more layouting (polish) loops in a lot of cases. This is ok because it is required to respect all the requirements of the components in a layout.

But it looks like this leads to a lot of additional events causing TalkBack to request a new or updates List of components. It feels like every geometry change causes this update. As example you can test https://play.google.com/store/apps/details?id=com.governikus.ausweisapp2&hl=en

Especially with slow devices and also with slow ChromesOS devices it sometimes takes more than a second until a new view is loaded and TalkBack accepts swiping through the components.

So the questions/request is: Can we avoid to send events causing TalkBack updates while polishing the layout and emit a single event after polish is done? Probably it is good to check/confirm my assumptions before.
