fix(huggingface): add stream_usage support for ChatHuggingFace invoke/stream

[girlsending0]

Description:
This PR fixes an issue where stream_usage metadata was not being returned during invoke or stream calls for HuggingFace chat models.
I updated ChatHuggingFace (via ChatHuggingFaceWithUsage) to align with BaseChatOpenAI behavior, ensuring usage information is properly included in streaming outputs.

Issue: N/A (but addresses missing usage metadata in HuggingFace integration).

Dependencies: None

Twitter handle: None
