Issue #18203: Replace malloc() with PyMem_RawMalloc() at Python initialization * Replace malloc() with PyMem_RawMalloc() * Replace PyMem_Malloc() with PyMem_RawMalloc() where the GIL is not held. * _Py_char2wchar() now returns a buffer allocated by PyMem_RawMalloc(), instead of PyMem_Malloc()

-Always use malloc() and free() directly in this file.  A number of these
-functions are advertised as safe to call when the GIL isn't held, and in
-a debug build Python redirects (e.g.) PyMem_NEW (etc) to Python's debugging
-obmalloc functions.  Those aren't thread-safe (they rely on the GIL to avoid
-the expense of doing their own locking).
