[GFC][Integration] min and max content height of the grid is size of rows and
gutters
https://bugs.webkit.org/show_bug.cgi?id=307713
rdar://170267496
Reviewed by Alan Baradlay.
The spec defines the min/max content height of the grid as the sum of
the rows and gutters.
https://drafts.csswg.org/css-grid-1/#intrinsic-sizes
The track sizes are outputted as part of GridLayout, so we need to make
sure that this is reflected on RenderGrid. This is because RenderGrid
treats height: auto always as max-content barring any overriding sizes
or something else computed by
RenderGrid::availableLogicalHeightForContentBox/RenderGrid::hasDefiniteLogicalHeight.
So if we see a MinContent or MaxContent constraint in the block axis,
which was determined by constraintsForGridContent, we should sum the
rows and gutters to make sure RenderGrid has its height set properly.
* Source/WebCore/layout/formattingContexts/grid/GridLayoutUtils.cpp:
(WebCore::Layout::GridLayoutUtils::totalGuttersSize):
Make this available to use outside of TrackSizingAlgorithm.
