  [IFC][Integration] Enable out-of-flow content with inline box containing box for IFC
https://bugs.webkit.org/show_bug.cgi?id=249370

Reviewed by Antti Koivisto.

This patch adds support for cases when the out-of-flow box's containing block is an inline box
e.g.
<div>
  <span style="position: relative">
    <div style="position: absolute></div>
  </span>
</div>

1. Move inline box logic from RenderBox::containingBlockLogicalWidth/HeightForPositioned to RenderInline
2. Implement the missing IFC support to compute the inner (padding) box of the first and last inline box.
3. Add IFC support in RenderInline::offsetForInFlowPositionedInline
