Describe the Enhancement

The METbaseimage issue dtcenter/METbaseimage#30 and corresponding MET pull request #3105 upgraded from Python 3.10 to 3.12. As noted in this PR comment that introduced some Python deprecation compiler warning messages that apparently first appeared in Python 3.11:

1. warning: ‘void Py_SetProgramName(const wchar_t*)’ is deprecated [-Wdeprecated-declarations] appears 20 times.
2. warning: ‘void PySys_SetArgv(int, wchar_t**)’ is deprecated [-Wdeprecated-declarations] appears 6 times.

Some options about the first one are discussed in Stack Overflow. It will apparently be fully removed from Python 3.15.

This issue is to update Python embedding code in MET to address these deprecation warnings.
