bpo-43931: Export Python version as API data (GH-25577)

Browse source 
When Python is embedded in other applications, it is not easy to determine which version of Python is being used. This change exposes the Python version as part of the API data. Tools like Austin (https://github.com/P403n1x87/austin) can benefit from this data when targeting applications like uWSGI, as the Python version can then be inferred systematically by looking at the exported symbols rather than relying on unreliable pattern matching or other hacks (like remote code execution etc...).

Thus ``3.4.1a2`` is hexversion ``0x030401a2`` and ``3.10.0`` is
hexversion ``0x030a00f0``.
This version is also available via the symbol :data:`Py_Version`.
.. c:var:: const unsigned long Py_Version
The Python runtime version number encoded in a single constant integer, with
the same format as the c:macro:`PY_VERSION_HEX` macro.
