Fix constant crash when setting MultiStateCallback.DEBUG_STATES=true

AbsSwipeUpHandler didn't increase STATE_NAMES size last time we added a
state. Changed to ArrayList to dynamically update the size, copied from
how GestureState does it, to avoid this issue in the future.

Test: Set DEBUG_STATES to true, verified logs when performing gestures
