Kumar Aditya 95e5d59630 gh-140414: add fastpath for current running loop in asyncio.all_tasks (#140542) 
Optimize `asyncio.all_tasks()` for the common case where the event loop is running in the current thread by avoiding stop-the-world pauses and locking.

This optimization is already present for `asyncio.current_task()` so we do the same for `asyncio.all_tasks()`.
