Recursive run_system (#18076) 
# Objective

Fixes #18030

## Solution

When running a one-shot system, requeue the system's command queue onto
the world's command queue, then execute the later.

If running the entire command queue of the world is undesired, I could
add a new method to `RawCommandQueue` to only apply part of it.

## Testing

See the new test.

---

## Showcase

```rust
#[derive(Resource)]
pub struct Test {
    id: SystemId,
    counter: u32,
}

let mut world = World::new();
let id = world.register_system(|mut commands: Commands, mut test: ResMut<Test>| {
    print!("{:?} ", test.counter);
    test.counter -= 1;
    if test.counter > 0 {
        commands.run_system(test.id);
    }
});
world.insert_resource(Test { id, counter: 5 });
world.run_system(id).unwrap();
```
