  [IFC] Maximum intrinsic width content caching should support "line-break: after-white-space"
https://bugs.webkit.org/show_bug.cgi?id=260568

Reviewed by Antti Koivisto.

"line-break: after-white-space" trims trailing whitespace in intrinsic width mode, while
preserves them in final layout.
This patch restores such trimmed whitespace content so that we can cache the layout result for subsequent layouts.
