Memory leak in _tuple_shared() on PyMem_Calloc() failure

[hyongtao-code]

Bug report

Bug description:

In _tuple_shared() (crossinterp_data_lookup.h), there is a memory leak when allocation of the items array fails. This only affects the OOM/error path.

Specifically:

    struct _shared_tuple_data *shared = PyMem_RawMalloc(...);
    ...
    shared->items = PyMem_Calloc(...);
    if (shared->items == NULL) {
        PyErr_NoMemory();
        return -1;
    }
