Relayout windows that handle their own config change.

Relayout windows that handle their own config change.

If a window claims to handle its own configuration change then we
won't destroy and recreate its window on a configuration change.
Normally that recreation triggers the first layout following
orientation change because mHaveFrame is false. Windows that handle
their own configuration changes never got a relayout pass following a
change in orientation.

This change passes the configuration changes that an application
handles into the AppWindowToken. If the app says it handles
orientation or screen size changes then a relayout will occur when the
configuration has changed.

Fixes bug 11647107.
