Refactor auto-fill
* Fix a layering issue where auto-fill manager which is in view
depended on activity which is in app
* Moved auto-fill classes to view or service based on their
purpose and removed dependecy on the classes in view to the
classes in service
* Push state to local auto-fill manager whether auto-fill is
enabled to avoid making IPC for every focus transition if
the user did not enable the feature
* Remove unnecessary offload to messages when handling calls
to auto-fill manager service as these are made over a oneway
interface and in general they do almost no work and typically
we do these on the binder thread
* Removed id from data set and fill response as the provider
can embed everything it needs to id them in the auth pending
intent
* Enforce the auth UI to be only an activity as this will work
with multi-window, recents, and back and also does not require
draw on top of other app special permission
* Authentication also no longer requires passing a remotable
callback to the auth activity but the activity handles the
request as if called for a result
* Handling stopping of a user to clean up in-memory state as
well as handling when a user gets unlocked as a provider may
be non-direct boot aware
* User the correct context when creating an auto-fill manager
* Move the receiver that listens for requests to hide system
windows to the manager service as the UI is a singleton and
no need every per-user state to register its own
* Removed extras from dataset as the only case a provider needs
to associate state with a dataset is for auth and the provider
can embed this data in the auth pending intent
