Lockscreen: Introduce window type TYPE_KEYGUARD_PANEL 

This window type will be used by third party keyguard components
so that they can be layered within the keyguard while running in
their own process.  This window type will use the same Z ordering
as TYPE_STATUS_BAR_SUB_PANEL, which is currently unused.
