gh-132775: Add _PyCode_GetVarCounts() (gh-133128)
This helper is useful in a variety of ways, including in demonstrating how the different counts relate to one another.

It will be used in a later change to help identify if a function is "stateless", meaning it doesn't have any free vars or globals.

Note that a majority of this change is tests.

The Python C API
================

The C API is divided into these sections:

1. ``Include/``: Limited API
2. ``Include/cpython/``: CPython implementation details
3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can
   change between minor releases
4. ``Include/internal/``, and any name with ``_`` prefix: The internal API

Information on changing the C API is available `in the developer guide`_
