  [IFC][initial letter] Initial letter line box sizing is based on capHeight
https://bugs.webkit.org/show_bug.cgi?id=250253

Reviewed by Antti Koivisto.

This patch is in preparation for supporting -webkit-initial-letter.
The inline letter's line box (it has its own container too) is based on the cap height of the primary font (alphabetic baseline only at this point).
