An flag to automatically compile all functions in a Python script using JIT and then run it. #8306

It would be nice if there were a flag to automatically compile all functions in a Python script using JIT and then run it, so the script wouldn't need to be modified—something like rustpython --jit script.py

BONUS: Maybe even add something like rustpython config jit true to permanently enable JIT in any script without --jit flag.
