Fix binding loop and polish issue in quick layout
The quick layout item cause binding loop issue when layout item size
were updated in-between polish. This has been fixed by not updating
layout size hint during rearrange.
But there is polish issue due to child item not being invalidated
and this skips corresponding item box size calculation. This patch
invalidate all the items in the rearrange list of the layout and
finally, invalidate engine and layout.
