gh-108223: Add [NOGIL] marker to sys.version by vstinner · Pull Request #108239 · python/cpython

If Python is configured with --disable-gil, add " [NOGIL]" suffix to
sys.version. It should help users to check if they are running a
regular Python build with a GIL, or a custom Python build with the
new experimental no GIL.

sys.version is commonly requested in bug reports: knowing if Python
was configured with --disable-gil should ease debug.

Example on Linux with --disable-gil:

    $ ./python -VV
