Replace HashSet with ArraySet in InputMethodSubtypeSwitchingController

There should be no user-visible bahavior change because
InputMethodSubtypeSwitchingController relies only on the following
three operations:
  * Collection#add()
  * Collection#remove()
  * Collection#contains()

There should be no behavior difference between HashSet and ArraySet
for those operations.
