### Summary
Onnx subgraph imports also should normalize and generate ty_info for its
ops, this is broken since the #19853 refactor.
### Issue
```
tests/python/relax/test_frontend_onnx.py:11581: in test_if_subgraph
tvm_model = from_onnx(model, keep_params_in_input=True)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/usr/lib/python3.15/site-packages/tvm/relax/frontend/onnx/onnx_frontend.py:6283:
in from_onnx
return g.from_onnx(graph, opset)
^^^^^^^^^^^^^^^^^^^^^^^^^
/usr/lib/python3.15/site-packages/tvm/relax/frontend/onnx/onnx_frontend.py:5823:
in from_onnx
self._construct_nodes(graph)
/usr/lib/python3.15/site-packages/tvm/relax/frontend/onnx/onnx_frontend.py:5969:
in _construct_nodes
then_expr = self._convert_subgraph(self.bb, attr["then_branch"])
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/usr/lib/python3.15/site-packages/tvm/relax/frontend/onnx/onnx_frontend.py:6166:
in _convert_subgraph
op = self._convert_operator(op_name, inputs, attr, self.opset)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/usr/lib/python3.15/site-packages/tvm/relax/frontend/onnx/onnx_frontend.py:6117:
in _convert_operator
sym = op_function(self.bb, inputs, attrs, [self._nodes, self._params])
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
/usr/lib/python3.15/site-packages/tvm/relax/frontend/onnx/onnx_frontend.py:1882:
in _impl_v11
ndim = len(inputs[0].ty.shape)
^^^^^^^^^^^^^^^^^^
E AttributeError: 'Type' object has no attribute 'shape'
```
### Fix
Onnx operator import check and normalize and populate the final relax op
with ty_info.
