AzureAIInference: support response format schema

[mathrb]

Is your feature request related to a problem? Please describe.
I'm using 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: microsoft/semantic-kernel#11025 (comment)

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?
