Haptics on pulling down the shade also consider remote user input.

When pulling down the shade from Launcer, the gesture is considered as a
remote initiation. This input also needs to be considered in the Flow
logic of SceneContainerHapticsViewModel to play haptics in this
particular case.

Test: added unit tests.
Test: Verify that flings in the homescreen play shade pull haptics for
  both single and dual shade modes
Flag: NONE extra haptics case to consider
