Add support for Apple Intelligence integrated ChatGPT

[vtta]

As the release of iOS 18.2 and macOS 15.2 Apple added the official support for invoking ChatGPT via Siri.
However, both the setup process (authentication via browser) and the conversation process (automatically invoking private ChatGPT API) have region lock, which need to be matched and proxied.
Under my testing, the current OpenAI rules cannot cover the domains used during above mentioned scenarios.
However, when enabling global proxy, the two process can proceed.
We need to identify the specific domains and add additional rules to cover such use cases.
