Evan Mattson 3d0a890e71 Python: Support OpenAI json_schema response format (#8958) ...

### Motivation and Context

OpenAI has released in their August 6th model the ability to specific a
json_schema response format. This allows the model to use the specified
Pydantic model or the provided JSON schema representing a "strict"
model/class to make sure that it responds with the exact schema that was
provided.

Note that the strict tool calling will be handled via a separate
ADR/work item once agreed upon by all three SK languages.

### Description

This PR introduces the ability to specific either a Pydantic model or a
non-Pydantic model for the json_schema response format
OpenAIChatPromptExecutionSettings.
- There are two new code sample concept files showing how to do this
with both a Pydantic and a non-Pydantic model. The other code sample
shows how to configure a json_schema response format while using
function calling.
- If the model is unable to respond based on the provided schema, it
will contain a `refusal` attribute as part of the chat completion
message contents. This will be included in the response as a TextContent
item explaining why it couldn't fulfill the request.
- Unit tests added for this new functionality.
- Handles #7946 

<!-- Describe your changes, the overall approach, the underlying design.
