See https://github.com/faster-cpython/ideas/issues/84

This appears to improve startup time by another 10% or more compared to main.

After PR 29118 is merged we get the benefits on UNIXy systems. We have several TODOs left then:

- (Definitely:) Generate Windows build files

- (Probably:) Find a way to avoid having to regenerate everything whenever any source file changes (any source file -> _bootstrap_python -> all generated files)

- (Maybe:) Consider putting all generated code together in one file, for more savings (and build simplification)
