When we added the session_lock_map, it resulted in pickling errors during Agent Engine deployment. To fix, we implemented custom getstate and setstate methods to exclude the lock map lock and session lock map from pickling. Closes https://github.com/google/adk-python/issues/4486.

meanwhile also centralize input-stream creation in registration
Move the LiveRequestQueue stream creation from _call_live
(function_tool.py) to the lazy registration block in
_process_function_live_helper (functions.py). This centralizes the
input_stream: LiveRequestQueue annotation check and stream creation
in one place, and ensures the stream is also recreated on
re-invocation after stop_streaming resets it to None.
_call_live now simply passes the existing .stream if set, without
needing to know about LiveRequestQueue at all.

**Description**
This PR resolves#4100 by making the `new_message` field optional in the `RunAgentRequest` model.
**The Problem:**
When attempting to resume an agent session via the FastAPI web server, the request would fail with a `422 Unprocessable Entity` if `new_message` was omitted. This prevented "resume-only" workflows where a user just wants to wake up an existing session.
**The Solution:**
Updated `RunAgentRequest.new_message` to be `Optional[types.Content] = None`. The underlying `runner.run_async` logic already supports `None` for resuming purposes, so no further logic changes were required.
**Verification:**
Verified that `RunAgentRequest` now validates successfully when `new_message` is missing, defaulting the field to `None`.
