Issue #3586472: Use ai provider configuration form element and use proper...
Description
This MR adds ai_provider_configuration form element to RestrictToTopic guardrails configuration form. The form element substitutes the old implementation of provider/model/config selection with AiProviderFormHelper service.
Testing instructions
- Create a Guardrail here
/admin/config/ai/guardrails - Use "Restrict to Topic" plugin
- Observe the "AI Provider" form element at the bottom of the page.
While doing this change I have also fixed the Subform State usage, as it was not properly done before in AI Guardrail Form. That is why the ajax inside ai_provider_configuration form element was not working properly.
