Reviewed by Alex Christensen.

Currently, key events rely on `FocusController` in the web process to determine which frame should receive
a key event. For site isolation, we should reference information on the focused frame stored in the UI
process so we can send the key event directly to the web process hosting the focused frame.

EventSenderProxyIOS::keyDown() is not implemented, so disable the test on iOS.
