  [IFC][hanging punctuation] Move trailing hanging content handling from LineBuilder to Line
https://bugs.webkit.org/show_bug.cgi?id=249650

Reviewed by Antti Koivisto.

1. reset trailing punctuation if the current line is not the last formatted line (trailing punctuation is not supposed to be hanging)
2. shrink the content logical width by the hanging content if in preferred width computation mode
