[css-contain] Size containment replaced elements intrinsic size is zero 

The spec is very clear about this
(https://drafts.csswg.org/css-contain/#containment-size):
  "Replaced elements must be treated as having an intrinsic width
   and height of 0."

The patch modifies LayoutReplaced::ComputeIntrinsicSizingInfo()
so that it returns zero for elements with "contain: size".
