[SysUI][Floaty] Adding squeeze effect haptics.

The new haptics mimic the previous assistant invocation haptics but also
take into account the new squeeze effect. To do so, a subtle rumble is
added as a pre-composition effect during the squeeze. The effect
culminates with the quick rise and tick haptics of the previous
assistant invocation as the Gemini floaty appears.

Test: SqueezeEffectHapticPlayerTest
Test: manual. Verified rumble haptics play during squeeze and play a
  rise and tick haptics with the Gemini Floaty.
Test: manual. Verified haptics are cancelled if the power button is
  released before a long-press is detected.
