  [IFC][Integration] Enable intrusive floats coming from rtl inline direction
https://bugs.webkit.org/show_bug.cgi?id=245528

Reviewed by Antti Koivisto.

Let's convert the incoming, intrusive float's directions (left, right, inline-start, inline-end) and coordinates to logical values (e.g. a left float should treated as "right" when the inline direction is rtl).
This enables the following type of content:
  <div style="direction: rtl">
    <img float-left>
    <div>this is rtl inline direction content with intrusive float box</div>
  </div>
