This is needed for tests.

This is also needed for tests.

Unfortunately, we cannot call Button::GetAccessibleName, because there is no
such thing. And we cannot call Button::GetAccessibleState, because it requires a
ui::AXViewState, and its constructor is in a separate DLL which is not linked
into the tests! Aarrghh!

So I just provide this separate method for tests to find out what the accessible
name will be.
