LibWeb: Use clip rectangles assigned to paintables in hit-testing

Browse source 
This change makes hit-testing more consistent in the handling of hidden
overflow by reusing the same clip-rectangles.

Also, it fixes bugs where the box is visible for hit-testing even
though it is clipped by the hidden overflow of the containing block.
