AX: VoiceOver ignores list content inside elements referenced by

Reviewed by Tyler Wilcock.
accessibleNameForNode() always passed DescendIntoContainers::No to
textUnderElement(), so list, table, tree and canvas children were skipped.
That heuristic exists so that a focusable container does not take its entire
inner
text as its own name, which is the right behavior when deriving a name
from content in the ordinary way. It is not right when the traversal
is an aria-labelledby or aria-describedby recursion: the ACCNAME spec
requires the text of the whole referenced subtree is included.
