[GFC] Finish resolveIntrinsicTrackSizesWithSpanningItems()
https://bugs.webkit.org/show_bug.cgi?id=322858
<rdar://186100312>
Reviewed by Sammy Gill.
This PR implements items 4-6 of
https://drafts.csswg.org/css-grid-1/#algo-spanning-items
Item 5 marks the tracks whose growth limit changed from infinite to finite in
that item. This is
done by updating distributeExtraSpace() to return the trackIndexes whose growth
limit is changed when
distributing extra space.
A RAII helper temporarily marks those tracks as infinitelyGrowable until it
goes out of scope after finishing item 6.
