Prefer walking the LayoutTreeBuilder tree when building the Accessibility tree.

This is in preparation for cl/1242572, which will include elements
with a display: contents style in the Accessibility tree.

Since display: contents means an element will not get a LayoutObject,
walking the Layout Tree means we miss some elements.
