Always propagate the reported proc_state to WindowProcessController.

When forceProcessStateUpTo() is used, we update the mRepProcState
but we don't propagate this to WindowProcessController which means
it won't always know when an app came out of the Cached state and
won't send any delayed configuration-changd event.
