wayland: Ignore plasma shell reposition requests during interactive move resize
Both kwin and plasma have different placement strategies during interactive move resize. That can result in the window flipping between two positions.
In order to prevent that, this change makes kwin placement take precedence over the window position specified using the plasmashell protocol. This can be considered as a workaround.
