Make StatusBar not be a NotificationPresenter

Break the NotificationPresenter out of the StatusBar and most of
the logic with it.

 - Break RemoteInput Callbacks out of NotificationPresenter
 - Break Environment Callbacks out of NotificationPresenter
 - Add ShadeController interface for StatusBar (abstraction
   layer from StatusBar)
 - Add InitController to allow for post-init tasks (dependency
 resolution should not go here)
 - Make some dependencies (ShadeController, NotificationEntryManager,
 NotificationLockscreenUserManager usually) lazily-resolved to break
 some dependency cycles

 - Lots of other cleanup

Test: Existing tests do not pass
