Pytorch wheel and libtorch building overview

This page gives an overview of the CI components that build wheels and libtorch archives for Pytorch. It shows Github Actions workflows, scripts, and produced artifacts, as well as elements of the build system.

While it is based on the new scikit-build-core based build system (which is not yet fully adopted), this only influences the lower part of the visualization; the upper part including the platform specific lanes apply equally to the setup.py based build system.
