Update layout tests to use Linkifier.linkInfo

https://crrev.com/c/2544131 renamed the method to remove the underscore
but shipped both names in order to avoid layout test breakages. Once
that's landed, we can land this change, and then remove the old
`_linkInfo` method as it will then be entirely unused.
