Removing the API, which was marked alpha in 0.3.0 and now is being removed. It is completely superseded by the Responses + Conversations APIs and our client-SDK Agent class is already updated to use those implementations. This PR performs a cleanup of dependent types and tests as well.

llamastack#4055 cleaned the agents implementation but while doing so it removed some tests which actually corresponded to the responses implementation. This PR brings those tests and assocated recordings back. (We should likely combine all responses tests into one suite, but that is beyond the scope of this PR.)

# What does this PR do? Restores the responses unit tests that were inadvertently deleted in PR [#4055 ](#4055) ## Test Plan I ran the unit tests that I restored. They all passed with one exception: tests/unit/providers/agents/meta_reference/test_openai_responses.py::test_reuse_mcp_tool_list AttributeError: module 'llama_stack.providers.utils.tools' has no attribute 'mcp' It's coming from this line: @patch("llama_stack.providers.utils.tools.mcp.list_mcp_tools") The mcp.py module (and \_\_init\_\_.py) exists under tools. There are some 'from mcp ....' imports (mcp package in this case) within it that python may be interpreting as circular imports (or maybe I'm overlooking something).
