feat(responses): add usage types to inference and responses APIs (#3764)
## Summary
Adds OpenAI-compatible usage tracking types to enable reporting token
consumption for both streaming and non-streaming responses.

## Type Definitions
**Chat Completion Usage** (inference API):
```python
class OpenAIChatCompletionUsage(BaseModel):
    prompt_tokens: int
    completion_tokens: int
    total_tokens: int
    prompt_tokens_details: OpenAIChatCompletionUsagePromptTokensDetails | None
    completion_tokens_details: OpenAIChatCompletionUsageCompletionTokensDetails | None
```

**Response Usage** (responses API):
```python
class OpenAIResponseUsage(BaseModel):
    input_tokens: int
    output_tokens: int
    total_tokens: int
    input_tokens_details: OpenAIResponseUsageInputTokensDetails | None
    output_tokens_details: OpenAIResponseUsageOutputTokensDetails | None
```

This matches OpenAI's usage reporting format and enables PR #3766 to
implement usage tracking in streaming responses.
