AzureAIInference: support response format schema

**Is your feature request related to a problem? Please describe.**
I'm using [semantic kernel](https://github.com/microsoft/semantic-kernel) for my prompts.
I've been using mostly Azure OpenAI models, which works fine for json structured output.
The issue I have is that, for a model like mistral, I can't get structured output working.
The reason is that AzureAIInference currently only support the "old way": json_object, no a specific format.
The issue was first opened on semantic-kernel repo: https://github.com/microsoft/semantic-kernel/issues/11025#issuecomment-2791460610

**Describe the solution you'd like**
AzureAIInference to implement a schema base response format so that it can be ported to semantic kernel.

**Describe alternatives you've considered**
Not using Azure models?
