Detectron2 installation error on Python 3.9

## Instructions To Reproduce the 🐛 Bug:
1. Full runnable code or full changes you made:
I didn't change anything. **_I have another conda enviroment in my machine, and I successfully installed detectron2 on this enviroment, the only difference is that this enviroment is using python 3.8._**
2. What exact command you run: python -m pip install -e detectron2 or python -m pip install 'git+https://github.com/facebookresearch/detectron2.git'
3. __Full logs__ or other relevant observations:
```

Start with setup.py around line 148 and reproduce the reported pip installation commands in a Python 3.9 environment. Inspect the native extension build configuration and the logged missing pybind11 headers, then compare it with the working Python 3.8 environment. Done means the reported installation succeeds or the supported dependency requirements are documented.
