fix(profiling): enable sub-classing wrapped lock types by custom lock implementations #15604

Zendesk ticket: https://datadog.zendesk.com/agent/tickets/2386207

Description

Fixes a bug where custom locks crash when inheriting from a wrapped lock type, when the profiler is enabled. In this case, user imported a third-party libraries neo4j which defines a class AsyncRLock inheriting asyncio.Lock (which we wrap).

A customer using neo4j v6.0.3 with ddtrace v4.0.0 reported their application failing to start:

...
  File "/usr/local/lib/python3.12/site-packages/neo4j/_async_compat/concurrency.py", line 45, in <module>
    class AsyncRLock(asyncio.Lock):
TypeError: _LockAllocatorWrapper.__init__() takes 2 positional arguments but 4 were given

The error occurred because neo4j's AsyncRLock class subclasses asyncio.Lock:

class AsyncRLock(asyncio.Lock):
    ...

Root Cause

When the profiler is enabled, it replaces lock classes (e.g., asyncio.Lock, threading.Lock) with _LockAllocatorWrapper instances to track lock usage. However, _LockAllocatorWrapper didn't implement __mro_entries__ (PEP 560), which Python requires when a non-type object appears in a class's bases.

When Python evaluates class AsyncRLock(asyncio.Lock): and asyncio.Lock is a _LockAllocatorWrapper instance (not a type), it tries to use the wrapper directly as a metaclass, leading to the TypeError.

Interestingly that using wrapt would not have prevented this bug, as it doesn't implement the __mro_entries__ either; so, removing this dependency didn't cause the issue.

Fix

Implement __mro_entries__ on _LockAllocatorWrapper to support PEP 560. This tells Python to use the original lock class as the actual base when subclassing.

Testing

Added a unit test: test_subclassing_wrapped_lock
manual test with a script located here
