  [IFC][hanging punctuation] Line::HangingContent should tell if the trailing content is conditionally hanging
https://bugs.webkit.org/show_bug.cgi?id=249713

Reviewed by Antti Koivisto.

"Stop or Comma" trailing content is conditionally hanging when hanging-punctuation is set to allow-end. However it is non-conditional when hanging-punctuation says "force-end".
In this patch, we start tracking if the trailing hanging content is conditional or not so that we can reset/trim them accordingly.
