Python code for the Hosted Workflows in AI Foundry

[LazaUK]

Motivation and Context

1. Why is this change required? Hosted workflows provide great capabilities to deploy, manage and consume multi-agent orchestration logic directly in Azure AI Foundry. So, sample code and YAML definition file can provide some insight into the mechanics of the process, and developers can then drive it further.
2. What problem does it solve? We currently have a great .Net sample. And this sample code can assist Python developers to achieve similar results.
3. What scenario does it contribute to? Hosted workflow capabilities in Azure AI Foundry
4. If it fixes an open issue, please link to the issue here. N/A

Description

All files were uploaded into new dedicated folder under /python/samples/getting_started/workflows/declarative/hosted-workflows, so there is no change to any existing content/code.

The upload consists of 6 files:

• Python script, to perform the agents and workflow creation;
• YAML file, to define workflow logic
• README.md, to describe the content, building blocks and execution
• 3 images, which are screenshots of AI Foundry's Agents and Workflows sections

Contribution Checklist

• The code builds clean without any errors or warnings
• The PR follows the Contribution Guidelines
• All unit tests pass, and I have added new tests where possible
• Is this a breaking change? If yes, add "[BREAKING]" prefix to the title of the PR.
