  [LFC][IFC] Decouple layout bounds and ascent/descent on inline level boxes
https://bugs.webkit.org/show_bug.cgi?id=246962

Reviewed by Antti Koivisto.

This is in preparation for supporting line-box-contain, where the layout bounds != ascent/descent.

Introduce setAscentAndDescent to set the ascent/descent. No functionality change here.
