LibWeb: Change StackingContext::hit_test() to accept callback
This change modifies hit_test() to no longer return the first paintable encountered at a specified position. Instead, this function accepts a callback that is invoked for each paintable located at a position, in hit-testing order. This modification will allow us to reuse this call for `Document.elementsFromPoint()` in upcoming changes.
