Fix dragging down notification shade handling over Glanceable Hub.

This changelist addresses a number of issues with notification shade
touch handling in glanceable hub:
- Properly handle cancel event to ShadeTouchHandler to end the touch
  session. not popping the touch session leads to a stale active
  session.
- Recreating the touch input session on the last popped session. This
  resets any pilfering logic that was tied to the original session.
- Only allow interactivity once the shade is expanded if the user is
  still interacting at full expansion.
- Begin tracking touches on move as well as done in the
  GlancealbeHubContainerController, as the original stream might be
  canceled but replaced with another source.
