  [IFC] Add isFirstFormattedLine to LineBuilder::LineContent
https://bugs.webkit.org/show_bug.cgi?id=248686

Reviewed by Antti Koivisto.

This is in preparation for support leading-trim on block level where line box sizing needs to know
whether the current line is the first formatted line (not enabled yet).
