[DO NOT MERGE] Use orientation value from config change event

Before, when the device was rotated we would get the new orientation value
from the event but then use the value from getResources() to decide
which layout to show. This discrepancy is a potential cause for an issue
where QS uses the landscape layout when the device was actually portrait

Test: atest QSPanelControllerBaseTest QSPanelControllerTest
