wenmeng zhou 5a6e1254a7 support return reasoning content for models like qwq in dashscope (#30317)
Thank you for contributing to LangChain!

- [x] **PR title**: "package: description"
- Where "package" is whichever of langchain, community, core, etc. is
being modified. Use "docs: ..." for purely docs changes, "infra: ..."
for CI changes.
  - Example: "community: add foobar LLM"

here is an example
```python
from langchain_community.chat_models.tongyi import ChatTongyi
from langchain_core.messages import HumanMessage

chatLLM = ChatTongyi(
    model="qwq-32b",   # refer to  https://help.aliyun.com/zh/model-studio/getting-started/models for more models
)
res = chatLLM.stream([HumanMessage(content="how much is 1 plus 1")])
for r in res:
    print(r)
```
