This patch take out initialization and delayed shutdown from
AutofillAssistantUiController:

 * initialization goes into a new class AutofillAssistantFacade, called
   from CustomTabActivity.

 * UiDelegateHolder becomes a toplevel class, responsible for delayed
   shutdown and UI pausing

The following responsibilities remain in AutofillAssistantUiController:

 * bridging Java -> C++ and C++ -> Java
 * account management and authentication

This patch also unifies the way the "give up" message is displayed in
Java, removes the unnecessary C++ OnGiveUp method and always hides the
overlay and the event filter when switching to graceful shutdown mode.
