[ty] Add hint if async context manager is used in non-async with statement (#18299) 
# Summary

Adds a subdiagnostic hint in the following scenario where a
synchronous `with` is used with an async context manager:
```py
class Manager:
    async def __aenter__(self): ...
    async def __aexit__(self, *args): ...

# error: [invalid-context-manager] "Object of type `Manager` cannot be used with `with` because it does not implement `__enter__` and `__exit__`"
# note: Objects of type `Manager` *can* be used as async context managers
# note: Consider using `async with` here
with Manager():
    ...
```
