  [IFC][Ruby] Position ruby base content (ruby-align: space-between)
https://bugs.webkit.org/show_bug.cgi?id=261647

Reviewed by Antti Koivisto.

This patch adds support for positioning the ruby base content _inside_ the ruby base container.
see https://drafts.csswg.org/css-ruby/#ruby-align-property
(To match legacy ruby, we only support "space-between" which maps to normal test justification/centering.)
