<pre>[css-grid] Pass GridSizingData instead of columnTracks to track sizing methods
https://bugs.webkit.org/show_bug.cgi?id=156466
Reviewed by Darin Adler.
Several methods used to compute the items' size contribution to the tracks they span in, get
as an argument a vector with the sizes of the column tracks.
In order to support grids with orthogonal flows (among other things) it's much better to
pass the GridSizingData struct and let those methods decide whether to use the columns or
the rows.
No new tests as this is just a minor refactoring with no change in behavior.
