A11ySemanticsRule class abstract

A check that runs against a SemanticsTreeWalker snapshot rather than an ElementTreeWalker one — the counterpart to A11yRule for issues that can only be caught by reading the actual accessibility tree (missing labels on widgets that set semantics via a custom RenderObject, focus order, ...).
