We actually don't move PyImport_Inittab. Instead, we make a copy that we keep on _PyRuntimeState and use only that after Py_Initialize(). We also prevent folks from modifying PyImport_Inittab (the best we can) after that point. #81057

The docs clearly say that ``PyImport_Inittab``, | ||
:c:func:`PyImport_AppendInittab`, and :c:func:`PyImport_ExtendInittab` | ||
should not be used after :c:func:`Py_Initialize` has been called. | ||
We now enforce this for the two functions. Additionally, the runtime | ||
now uses an internal copy of ``PyImport_Inittab``, | ||
to guard against modification. |
