[MathML] Support CSS size containment with contain-intrinsic-size properties
https://bugs.webkit.org/show_bug.cgi?id=304018
rdar://166323213
Reviewed by Alan Baradlay.
Implement support for CSS Containment's size containment in MathML
elements. When contain: size or contain: inline-size is specified along
with contain-intrinsic-inline-size or contain-intrinsic-block-size, use
these explicit intrinsic sizes instead of computing from content.
This enables MathML elements to participate in size containment
optimizations, matching the behavior of other CSS layout models.
