core: auto-discover models from OpenAI-compatible local providers

[Qard]

What does this PR do?

Attempts to auto-discover models from OpenAI-compatible providers to allow local LLM providers like Ollama and LM Studio to show their model list without needing to manually add each model. This does not auto-discover the provider itself nor does it modify model entries which already exist, so this should be non-destructive with any already provided model data.

How did you verify your code works?

I ran this locally against my Ollama instance and it showed all my local models, switching to models with auto-generated configs worked just fine with this change.
