Fix 2428368: Fix most of the lockscreen orientation refresh bugs

This change removes the legacy notification of orientation and configuration changed events
from KeyguardUpdateMonitor and moves them into the individual activities.  This was necessary
to guarantee order of events.

In addition, to minimize discrepencies due to notification lag, Keyguard screens (LockScreen,
PatternUnlock, etc.) are now responsible for handling onConfigurationChanged() notification and
forwarding them to LockPatternKeyguardView by a call to recreateMe() with the new configuration.
