Before Python 3.10, asyncio.Queue() required a running event loop at creation time. This was deprecated in 3.8-3.9 and fully removed in 3.10. ADK requires Python 3.10+, thus remove this unecessary logic

Final part of https://github.com/google/adk-python/discussions/3605.
This change introduces:
- A new `adk migrate session` CLI command to run database schema upgrades.
- A migration script to upgrade from the old Pickle-based session schema (v0) to the new JSON-based schema (v1).
- A migration runner that orchestrates the upgrade process, handling sequential migrations and using temporary SQLite databases for intermediate steps if needed.
- Unit tests for the v0 to v1 migration.

This change modifies `load_dotenv_for_agent` to first capture the environment variables already set in the process. After loading the `.env` file with `override=True`, it restores the values of these initially set variables, ensuring that explicitly set environment variables are not overwritten by the `.env` file. A new environment variable, `ADK_DISABLE_LOAD_DOTENV`, is also introduced to completely skip the `.env` loading process
