[ty] Add a diagnostic for @functools.total_ordering without a defined comparison method (#22183)

## Summary

This raises a `ValueError` at runtime:

```python
from functools import total_ordering

@total_ordering
class NoOrdering:
    def __eq__(self, other: object) -> bool:
        return True
```

Specifically:

```
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/functools.py", line 193, in total_ordering
    raise ValueError('must define at least one ordering operation: < > <= >=')
ValueError: must define at least one ordering operation: < > <= >=
```

 ## Missing ordering method
 
 If a class has `@total_ordering` but doesn't define any ordering method (itself or in a superclass),
-the decorator would fail at runtime. We don't synthesize methods in this case:
