Minor cleanup of dismiss action interactor to hide state that it doesn't have to expose.

 - Hides internals of the interactor as private properties and makes the interactor "activateable"
 - The interactor is now responsible for orchestrating the execution of the dismiss action based on various triggers, this was being done by KeyguardDismissActionBinder before
 - Also invokes notifyKeyguardAuthenticatedHandled to reset biometric authenticated state stored in KeyguardBouncerRepository, this was previously done by KeyguardBouncerViewBinder
