feat: Add LlamaFile support

Add support for LlamaFile, a new model provider that allows users to interact with models stored in LlamaFile format. This includes:

- Adding an icon for LlamaFile in the provider selection menu.
- Updating the model provider selection to include LlamaFile.
- Updating the model handling logic to properly identify and process LlamaFile models.
- Updating the API providers list to include LlamaFile.

This enables users to leverage the capabilities of LlamaFile models within the application.
