blink: Avoid redundant paint clip nodes for images.

The ImagePainter is optimized to clip painted images to the content box
(which is the default case). This avoids the need to track additional
clip nodes in paint property trees which in turn enable optimizations
later in the stack. This regressed with CSSOverflowForReplacedElements
and this change restores the old behaviour.

crbug.com/1355971 tracks the follow up work to implement the folding
optimization in CC for the cases where the clip node can't be optimized
out.
