Request: cpython

Like https://github.com/python-cmake-buildsystem/python-cmake-buildsystem (same motivation)

Upstream cpython is not very interested in alternative build systems and the current way to build python for wasm or to statically link it are not quite easy to use (e.g. https://wiki.python.org/moin/BuildStatically or https://pythondev.readthedocs.io/wasm.html).

A basic python build, without pip and even without parts of the std which could just target wasm-unknown would be a good starting point, similar options to the cmake version are probably sensible for future enhancements.

Start by reviewing the linked python-cmake-buildsystem project and the CPython static-build and WebAssembly references in the issue. Determine the scope and options for a basic CPython build targeting wasm-unknown without pip and with a reduced standard library; the issue does not name repository files, tests, or a more specific acceptance criterion.
