Prepare for Python "Limited API" in PL/Python
Using the Python Limited API would allow building PL/Python against
any Python 3.x version and using another Python 3.x version at run
time. This commit does not activate that, but it prepares the code to
only use APIs supported by the Limited API.
Implementation details:
- Convert static types to heap types
(https://docs.python.org/3/howto/isolating-extensions.html#heap-types).
- Replace PyRun_String() with component functions.
- Replace PyList_SET_ITEM() with PyList_SetItem().
