Move catcher trail generation logic to Catcher

It resolves mutual dependency of `Catcher` and `CatcherTrailDisplay`.
Trail generation logic is moved to `Catcher`.
The generation logic no longer uses delayed scheduling because the hidden state is hard to manage.
Instead, the last time a trail is generated is calculated and used.
The new logic has a different behavior when the dash key is pressed in succession under 50ms, but it is not noticeable for normal plays.
