Track callsite for observers & hooks (#15607)
# Objective

Fixes #14708

Also fixes some commands not updating tracked location.


## Solution

`ObserverTrigger` has a new `caller` field with the
`track_change_detection` feature;
hooks take an additional caller parameter (which is `Some(…)` or `None`
depending on the feature).

## Testing

See the new tests in `src/observer/mod.rs`

---

## Showcase

Observers now know from where they were triggered (if
`track_change_detection` is enabled):
```rust
world.observe(move |trigger: Trigger<OnAdd, Foo>| {
    println!("Added Foo from {}", trigger.caller());
});
```

## Migration

- hooks now take an additional `Option<&'static Location>` argument
