[LFC][TFC] Cache table's width constraint values.
https://bugs.webkit.org/show_bug.cgi?id=203135
<rdar://problem/56396352>

Reviewed by Antti Koivisto.

This patch ensures that when computedIntrinsicWidthConstraints is called from both the preferred width and the actual layout codepaths during a layout frame, we don't
end up building up the grid twice.
