Make no-history activity be finished with different tasks

Activities that specify No History must be removed once the user
navigates away from them. Currently, the no-history activity is
managed in Task level which result in the behavior broken when a
fullscreen activity was started on top of the no-history activity
within different tasks.

This CL make the no-history instance cached reference from
TaskSupervisor and support task to manage the behavior. The
no-history activity will be finished only from the same
display with the next top-most opaque activity.
