gh-128341: Use _Py_ABI_SLOT in stdlib modules (#145770)

Rename from _Py_INTERNAL_ABI_SLOT to _Py_ABI_SLOT
and define the macro using _PyABIInfo_DEFAULT.

Use the ABI slot in stdlib extension modules to enable running
a check of ABI version compatibility.

_tkinter, _tracemalloc and readline don't use the slots, hence they need
explicit handling.
