Keyguard presentations are shown on external displays and are not
touch explorable.
Fixes bug 18831402

This change achieves a couple of things:
- Let Keyguard be a library, so we can use it in SystemUI.
- Introduce FLAG_KEYGUARD for windows and deprecate TYPE_KEYGUARD. Make
all the TYPE_KEYGUARD behaviour dependant on the flag.
- Implement a new KeyguardService in SystemUI, and bind that service
from PhoneWindowManager.
- Introduce BaseStatusBar.setKeyguardState and inflate
KeyguardSimpleHostView there and use FLAG_KEYGUARD for the window, such
that the status bar window essentially gets the Keyguard.
