Pointer icon refactor for touch

When PointerChoreographer is enabled, PointerChoreographer can
create multiple TouchPointerControllers for each touch device
when 'Show taps' is enabled. A TouchPointerController is
reponsible for one touch device and it can show touch spots
on the associated display.
