Merge to M58: AXObject::performDefaultAction() should focus if it can't click

Merge to M58: AXObject::performDefaultAction() should focus if it can't click

The user-visible bug here is that sending a CLICK event to a text field on
Android does nothing, because a text field doesn't have a default action.

I could fix this on the Android side, but this seems wrong to me. If
performDefaultAction() is called on a focusable control, I think the natural
thing to do is focus it if there's no "press" behavior. So I think we should
handle that generally.

Let me know if you have any objection and I could make it more narrow. But to
me it seems more useful this way.
