Apply new keyguard orientation when it becomes non-rotatable

Notification shade window didn't update its orientation
layout params sometimes when switching displays,
it worked only if there was a coincidental call
about other state change right after display switch.
Added explicit applying of the state if the value
of the resource that shows if the rotation is allowed
has changed.

Bug: 216622540
Test: atest com.android.systemui.statusbar.phone.NotificationShadeWindowControllerImplTest
Test: manually fold several times from portrait
 orientation on the inner screen to AOD screen
