Windows11Style: fix drawing rounded corners in itemviews

Browse Source 
When drawing an itemview item, the rounded corners (for current and
hovered item) were not properly drawn - the rounded corners of the
windows11 style were sometimes also visible where they should not be.
Fix it by using a clip rect and move the rounded corners out of the clip
rect on the appropriate places.

Pick-to: 6.9
Task-nubmer: QTBUG-131585
