WinPython internal progress follow-up

• Winpython-3.13.0b1
  • moving to wppm command line makes it compatible
  • we have for the build to patch tempfile.py and copy python-3.13t.exe as python.exe
  • pip-23.2 works for source packages
  • problems:
    • no IDLE/TKINTER: free-threading implementation unfinished
    • slow:
      • only 40% more performant in total with 4 threads
      • python-3.13.0b1 free-threading doesn't activate the weak reference counting yet,
    • binary wheels toolchain, and pip-24.1 not yet there
• WinPython-3.13.0b1b:
  • add ptpython to have in "WinPython Interpreter.exe" the equivalent of cpython-3.13 REPL on linux, and compensate IDLE loss: with jedi and latest parso-0.8.4
  • add interpreters_pep_734 and examples (miss the channel example)
  • add pyperf-2.7.0 that may be usefull to run examples
  • tweak examples from@FeldrinH remarks
