  [IFC][Ruby] Add skeleton implementation for ruby overhang
https://bugs.webkit.org/show_bug.cgi?id=261857

Reviewed by Antti Koivisto.

Ruby overhang lets the non-overlapping annotation box overhang adjacent inline content on the line (before/after).
1. Collect base start/end(last content box) display boxes
2. Consult RubyFormattingContext for overhang value(s)
3. Adjust display box horizontal position as needed
