Issue #18874: _PyObject_Malloc/Realloc/Free() now falls back on

_PyMem_RawMalloc/Realloc/Free, instead of _PyMem_Malloc/Realloc/Free.  So it
becomes possible to use the fast pymalloc allocator for the PYMEM_DOMAIN_MEM
domain (PyMem_Malloc/Realloc/Free functions).

Python has a *pymalloc* allocator for allocations smaller than 512 bytes. This
allocator is optimized for small objects with a short lifetime. It uses memory
mappings called "arenas" with a fixed size of 256 KB. It falls back to
:c:func:`PyMem_Malloc` and :c:func:`PyMem_Realloc` for allocations larger than
512 bytes. *pymalloc* is the default allocator used by
:c:func:`PyMem_RawMalloc` and :c:func:`PyMem_RawRealloc` for allocations larger
than 512 bytes. *pymalloc* is the default allocator used by
:c:func:`PyObject_Malloc`.
The default arena allocator uses the following functions:
