Python: Add Scaffolding for Durable AzureFunctions package to Agent Framework

[larohra]

Motivation and Context

This PR introduced the scaffolding for adding Durable AgentFunctions package to Agent Framework. This would add a durability layer on top of the Agent Framework SDK.

Description

Currently this just captures the scaffolding similar to how other packages are defined. I'll slowly keep adding more relevant files here.
