Python: Agent response callbacks to provide full context

[TaoChenOSU]

Motivation and Context

Currently, the agent response callbacks in the Orchestrations are triggered only when the final responses from the agents become available. This limits developers to create solutions that can expose the internal processing of the agents in multi agent orchestrations.

Description

The callbacks will now be triggered by the intermediate messages of the agents:

1. A new sample
2. Tests

P.s. Fix a bug where the name of the intermediate messages is not assigned.

Contribution Checklist

• The code builds clean without any errors or warnings
• The PR follows the SK Contribution Guidelines and the pre-submission formatting script raises no violations
• All unit tests pass, and I have added new tests where possible
• I didn't break anyone 😄
