  [IFC][hanging punctuation] Add punctuation/stop/comma utility functions to TextUtil
https://bugs.webkit.org/show_bug.cgi?id=249543

Reviewed by Antti Koivisto.

This is in preparation for supporting "hanging-punctuation" property.
(Line builder/breaker is going to use these functions to check if the candidate content
has any hangable leading/trailing characters -as they should not be taken into account for line content fit).
