Fork out Masonry into a separate layout function
https://bugs.webkit.org/show_bug.cgi?id=251459

Reviewed by Matt Woodrow.

I have been finding a significant amount of special cases are getting added to
the grid code to handle masonry. This has been getting rather messy to maintain,
and splitting these two would allow easier changes to the layout to support masonry without
worrying about breaking grid.
