Fetch models for China AI PC Dev Kit users

[ibelem]

The models are inaccessible from huggingface.co in China, we need to solve this issue.

1. Please check if we can switch the domain from https://huggingface.co to https://hf-mirror.com/ for Chinese users.
2. See if we can load https://modelscope.cn/ via fetch API.

How can we detect if the user is coming from China on the Web?

1. The https://ipinfo.io/ need to pay for the API access
2. The Google Maps Geocoding API requires user's permissions for accessing Geolocation API at first

Both hf-mirror and modelScope restrict the cross-domain access, fetching resource directly is not available. So the solution is to require users to manually download model files and upload through the load models locally button in UI
