layout: Allow transforming inline replaced elements (#31833)

Browse source 
This requires passing through information about whether or not the
element in question is replaced when checking to see if it's
transformable and transitively all functions that make decisions about
containing blocks. A new FragmentFlag is added to help track this -- it
will be set on both the replaced items BoxFragment container as well as
the Fragment for the replaced item itself.

Fixes #31806.
