- Use `FxHashMap` for `active_pointer_ids`
- Refactor and fix logging message for touch, especially
`update_active_touch_points_when_early_return`
- Randomly fix some typos
Testing: This changes logging message but no other observable
behaviours. The logging should be more accurate, but I didn't test.
