This gains 10% or more in startup time for `python -c pass` on UNIX-ish systems.

The Makefile.pre.in generating code builds on Eric's work for bpo-45020, but the .c file generator is new.

Windows version TBD.

…0 KB space (GH-31074)

This reduces the size of the data segment by **300 KB** of the executable because if the modules are deep-frozen then the marshalled frozen data just wastes space. This was inspired by comment by @gvanrossum in #29118 (comment). Note: There is a new option `--deepfreeze-only` in `freeze_modules.py` to change this behavior, it is on be default to save disk space.
