Add supportsDismissingSelfWindow attribute of IME
When a virtual keyboard is shown on some configurations (e.g. Phone),
the System UI may change the back navigation button to a different UI
element in order to dismiss the virtual keyboard. Such UI modification
is unnecessary when the virtual keyboard has a dismissing button on
its own window. This new attribute hints the System UI that the
virtual keyboard may have a UI element to dismiss itself. This will be
also useful for Tablet System UI which may not show a navigation bar
when a virtual keyboard is shown.
