gh-57684: Add -P cmdline option and PYTHONSAFEPATH env var (#31542)

2022-05-05T23:34:11Z

Add the -P command line option and the PYTHONSAFEPATH environment
variable to not prepend a potentially unsafe path to sys.path.

* Add sys.flags.safe_path flag.
* Add PyConfig.safe_path member.
* Programs/_bootstrap_python.c uses config.safe_path=0.
* Update subprocess._optim_args_from_interpreter_flags() to handle
  the -P command line option.
* Modules/getpath.py sets safe_path to 1 if a "._pth" file is
  present.

bpo-45950: Introduce Bootstrap Python again (#29859)

2021-12-03T15:01:11Z

The build system now uses a :program:`_bootstrap_python` interpreter for
freezing and deepfreezing again. To speed up build process the build tools
:program:`_bootstrap_python` and :program:`_freeze_module` are no longer
build with LTO.

Cross building depends on a build Python interpreter, which must have same
version and bytecode as target host Python.
