Making ShadeInteractor aware of user interactions remotely initiated.

A user swipe that originates remotely (i.e., in Launcher) and continues
to be processed in System UI is still a user-generated gesture. The
ShadeInteractor should consider this event as well in the
isUserInteracting Flow. Consolidating this upstream logic also makes the
shade pull haptics logic simpler.

Test: refactored Unit tests.
Test: manual. Verified shade pull haptics continue to work when swiping
  and flinging from the homescreen, status bar, and lockscreen (with
  dual and single shade)
