The `InputEvent` class currently supports the `pressed` and `released` states, which given the binary nature, is represented by a `bool` field. This commit introduced the `CANCELED` state, which signals that an ongoing input event has been canceled. To represent all the states, the `InputEventState` enum is added and the `InputEvent` logic is refactored accordingly.
