feat: add SiliconCloud provider support

- Add SiliconCloud provider implementation based on OpenAI-compatible API
- Support multiple API endpoints (China, China-overseas, International)
- Add model definitions with region-specific pricing
- Integrate with UI settings and validation
- Add i18n translations for SiliconCloud settings

Closes #8550
