Reduce distribution size with install-only-stripped builds

[Coruscant11]

Hello! 👋

Since the 20240726 release of python-build-standalone, a new kind of distributions builds are available.

A new install_only_stripped variant is now included in the release (https://github.com/indygreg/python-build-standalone/pull/279). These builds are constructed by taking the install_only variant for each platform and stripping any debug symbols. The resulting builds are significantly smaller, especially on Windows and Linux, but omit debugging symbols. The install_only builds continue to preserve such symbols.

=> Smaller binaries with embeded distributions, and smaller downloads 🚀

Some examples:

I will make a related pull-request 🙂
