Generalize StateTransitionEvent<S> to allow identity transitions (#13579) 
# Objective

This PR addresses one of the issues from [discord state
discussion](https://discord.com/channels/691052431525675048/1237949214017716356).
Same-state transitions can be desirable, so there should exist a hook
for them.

Fixes https://github.com/bevyengine/bevy/issues/9130.

## Solution

- Allow `StateTransitionEvent<S>` to contain identity transitions.
- Ignore identity transitions at schedule running level (`OnExit`,
`OnTransition`, `OnEnter`).
- Propagate identity transitions through `SubStates` and
`ComputedStates`.
- Add example about registering custom transition schedules.

## Changelog

- `StateTransitionEvent<S>` can be emitted with same `exited` and
`entered` state.
