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?

まず、Python モジュール _sysconfigdata を生成および使用する sysconfig の内部実装を読み、その後、関連する PR gh-127180、gh-127302、gh-128558 を確認してください。設定データが JSON として表現され、sysconfig.get_config_vars() が引き続き動作し、ツールが Python コードを実行せずにインストールを検査できれば完了です。
