[Swift shipping] Implement device testing framework

AI-driven testing bot

This bot helps discover new, real-world test cases based on the Swift SDK frameworks. The goal is to introduce an AI-driven github testing bot that identifies new real-world usage patterns based on projected APIs from Swift SDK frameworks.

There are two main features: (1) to help development, run the bot on PRs to discover new use cases introduced by the PR; (2) to instruct end-users, generate projections from provided Swift code snippet.

Functional requirements:

• The bot shall be able to run projection tooling against all frameworks within the SDK
• The bot shall be able to run projection tooling against a provided Swift code snippet
• The bot shall be able to generate small real-world use cases based on provided APIs
• The bot shall be able to run generated bindings and report results
• The bot shall be able to report the number of newly supported types and methods per framework for a PR
• The bot shall be able to validate proposed end-user scenarios against existing functional tests to avoid redundancy
