  [IFC][Ruby] Introduce Ruby Formatting Context

Reviewed by Antti Koivisto.

RFC is responsible for laying out the "ruby container" subset of inline items.
(RubyFormattingContext is not derived from FormattingContext as it is not a traditional formatting context like block, flex etc, as its content participates in the parent IFC too.)
