bpo-35368: Make PyMem_Malloc() thread-safe in debug mode (GH-10828)
When Python is compiled in debug mode, PyMem_Malloc() uses debug
hooks, but it also uses pymalloc allocator instead of malloc().
Problem: pymalloc is not thread-safe, whereas PyMem_Malloc() is
thread-safe in release mode (it's a thin wrapper to malloc() in this
case).
Modify the debug hook to use malloc() for PyMem_Malloc().
