bpo-45873: Get rid of bootstrap_python by gvanrossum · Pull Request #29714 · python/cpython

@gvanrossum

Instead we use $(PYTHON_FOR_REGEN) .../deepfreeze.py with the
frozen .h file as input, as we did for Windows in bpo-45850.

We also get rid of the code that generates the .h files
when make regen-frozen is run (i.e., .../make_frozen.py).
