  [MLIR][Python] Support type definitions in Python-defined dialects (#182805)

In this PR, we added basic support of type definitions in Python-defined
dialects, including:
- IRDL codegen for type definitions
- Type builders like `MyType.get(..)` and type parameter accessors (e.g.
`my_type.param1`)
- Use Python-defined types in Python-defined oeprations

```python
class TestType(Dialect, name="ext_type"):
    pass

class Array(TestType.Type, name="array"):
    elem_type: IntegerType[32] | IntegerType[64]
    length: IntegerAttr

class MakeArrayOp(TestType.Operation, name="make_array"):
    arr: Result[Array]

class MakeArray3Op(TestType.Operation, name="make_array3"):
    arr: Result[Array[IntegerType[32], IntegerAttr[IntegerType[32], 3]]]
```
