[css-grid] Introduce AncestorSubgridIterator
https://bugs.webkit.org/show_bug.cgi?id=263262
rdar://117083828
Reviewed by Matt Woodrow.
This patch adds an iterator that can be used to traverse a chain of
ancestor subgrids and also uses it in a few different places where it
can be used. The iterator is very similar to the RenderAncestorIterator,
but the main difference is that we need to check if the next ancestor
we are traversing is a subgrid in the appropriate direction.
There are two main ways to use the iterator:
1.) Providing the first subgrid ancestor that will be used in the
traversal along with the traversal direction.
2.) Using the ancestorSubgridsOfGridItem helper function. This is
useful when you have a subgridded item that you want to traverse the
ancestor subgrids of.
