Restructure the agent_sdks folder

The code is reorganized with the following structure
```
agent_sdks/python
- src/a2ui
  - core
    - schema
      - manager.py
      - validation.py
      - payload_fixer.py
      - ...
    - template
      - ...
    - inference_stategy.py
  - adk
    - a2a_extension
      - a2ui_extension.py
      - send_a2ui_to_client_toolset.py
```

Tested:
- [x] All individual sample ADKs are working with connected client.
- [x] The orchestrator sample is also working with all sub-agents.
