  [MLIR][Python] Allow `Attribute` to denote unconstrained attributes in Python-defined ops (#224679)

Operation definitions support attribute constraints such as
`IntegerAttr`, `StringAttr`, and `IntegerAttr | StringAttr`, but
currently reject `Attribute` itself.

This change allows `Attribute` to denote an unconstrained attribute,
accepting both built-in and Python-defined attributes:

```python
class MyOp(MyDialect.Operation, name="my_op"):
    arg: Operand
    attr: Attribute
    res: Result
```

This complements the unconstrained `Operand` and `Result` annotations
introduced in #220216. The annotation also works with `attribute()`
field specifiers, including `kw_only` and `default_factory`.
