ViewRootImpl: Ensure layout when configuration changes.

When the configuration changes between landscape and reverse
landscape, the app will not receive onConfigurationChanged as
orientation is not part of the public portion of the configuration.
However, when the ViewRootImpl receives such a configuration back from
relayout, it will force a layout of the client views
(see updatedConfiguration in performTraversals), this is because
Configuration#equals compares the non public part of the configuration
as well. This CL changes MSG_REPORT_RESIZED to handle the configuration
changing the same way performTraversals does, so that the app consistently
receives a configuration change.
