Handle all white-space values when intrinsically sizing an IFC
Browse files Browse the repository at this point in the history 
There were various cases like `text-wrap-mode: nowrap` and
`white-space-collapse: break-spaces` that weren't handled well.

Fixes #33335

flexbox_flex-formatting-interop.html fails now because we don't support
`table-layout: fixed`.
