Convert `_sysconfigdata` to a JSON file

Feature or enhancement

Proposal:

Currently, as part of the sysconfig internals, we generate a _sysconfigdata Python module containing the variables for sysconfig.get_config_vars(). This data is consists of all Makefile variables, which can be encoded as JSON data.

The use of a module instead of a text file is historic, and adds unnecessary complexity. Converting _sysconfigdata to a JSON file would simplify the sysconfig implementation. Additionally, it also makes it easier for tools to introspect the Python installation, as this would remove the necessity to execute Python code to read _sysconfigdata.

Has this already been discussed elsewhere?

Beginne mit der Lektüre der sysconfig-Interna, die das Python-Modul _sysconfigdata erzeugen und verwenden, und prüfe anschließend die verknüpften PRs gh-127180, gh-127302 und gh-128558. Die Aufgabe ist abgeschlossen, wenn die Konfigurationsdaten als JSON dargestellt werden, sysconfig.get_config_vars() weiterhin funktioniert und Tools die Installation untersuchen können, ohne Python-Code auszuführen.
