[GFC] Support fixed-length padding on grid items
https://bugs.webkit.org/show_bug.cgi?id=319430
<rdar://182249991>
Reviewed by Sammy Gill.
Narrow and rename the padding avoidance reason (now
GridItemHasPercentOrCalcPadding)
so grid items whose padding is a fixed length (px, em, etc) use GFC instead of
the
legacy RenderGrid.
Fixed-length padding is threaded into item and track sizing as part of the
item's border-box size, so it lays out identically to legacy RenderGrid.
Percentage and calc() padding remain on the legacy path for now.
