[GFC] Handle percentage and calc specified size suggestion.
https://bugs.webkit.org/show_bug.cgi?id=312409
<rdar://174863227>
Reviewed by Sammy Gill.
Per https://drafts.csswg.org/css-grid-2/#specified-size-suggestion:
"If the item’s preferred size in the relevant axis is definite, then the
specified size suggestion is that size. It is otherwise undefined.""
This PR updates GridLayoutUtils to handle inline and block specified
size suggestions for percentage and calc sizing. Previously percent
and calc preferred size would hit ASSERT_NOT_IMPLEMENTED_YET().
This PR also pipes sizes needed to resolve percent and calc values.
