gh-143650: Fix importlib race condition on import failure (GH-143651)
Fix a race condition where a thread could receive a partially-initialized
module when another thread's import fails. The race occurs when:
1. Thread 1 starts importing, adds module to sys.modules
2. Thread 2 sees the module in sys.modules via the fast path
3. Thread 1's import fails, removes module from sys.modules
4. Thread 2 returns a stale module reference not in sys.modules
The fix adds verification after the "skip lock" optimization in both Python
and C code paths to check if the module is still in sys.modules. If the
module was removed (due to import failure), we retry the import so the
caller receives the actual exception from the import failure rather than
a stale module reference.

Fix thread-safety issues when accessing frame attributes while another
thread is executing the frame:
- Add critical section to frame_repr() to prevent races when accessing
the frame's code object and line number
- Add _Py_NO_SANITIZE_THREAD to PyUnstable_InterpreterFrame_GetLasti()
to allow intentional racy reads of instr_ptr.
- Fix take_ownership() to not write to the original frame's f_executable

* gh-140414: add fastpath for current running loop in `asyncio.all_tasks` (GH-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()`.
