Enhance critical section held assertions for objects in free-threading

[kumaraditya303]

Currently the critical section held assertions on objects are not helpful as it doesn't prints the object of which the critical section should be held, it is helpful for debugging to print the object along with a message that critical section of object is not held.

Before:

❯ ./python -m test test_asyncio
Using random seed: 3111514708
0:00:00 load avg: 21.32 Run 34 tests sequentially in a single process
0:00:00 load avg: 21.32 [ 1/34] test_asyncio.test_base_events
python: ./Include/internal/pycore_critical_section.h:236: void _PyCriticalSection_AssertHeld(PyMutex *): Assertion `cs != NULL && cs->_cs_mutex == mutex' failed.
Fatal Python error: Aborted

After:
