cli.version: Show information about free-threaded-ness

Now you see information like

   $ pyeclib-backend -V
   pyeclib 1.7.0
   liberasurecode 1.7.1
   CPython 3.14.0rc2 free-threading build

or

   $ pyeclib-backend -V
   pyeclib 1.7.0
   liberasurecode 1.7.1
   CPython 3.13.7 experimental free-threading build

on free-threaded builds instead of just

   $ pyeclib-backend -V
   pyeclib 1.7.0
   liberasurecode 1.7.1
   CPython 3.14.0rc2
