Replace `pyvenv.cfg`'s `home` key with `base-prefix` and `base-exec-prefix`

Feature or enhancement

Proposal:

The home key in pyvenv.cfg is used to specify the directory where the base Python executable is. During the Path Initialization, this directory, and consecutively its parents, is searched for stdlib landmarks to determine sys.base_prefix and sys.base_exec_prefix. Naturally, this isn't ideal, it would be better if pyvenv.cfg contained these values directly.

Proposed plan:

• Update venv to start setting the base-prefix and base-exec-prefix keys in pyvenv.cfg when creating/updating environments
• In getpath, use the base-prefix and base-exec-prefix keys to set the prefixes
• Deprecate specifying home, in pyvenv.cfg

Has this already been discussed elsewhere?

Comienza leyendo la lógica de creación y actualización del entorno venv y, a continuación, sigue la Path Initialization en getpath para ver cómo pyvenv.cfg determina actualmente sys.base_prefix y sys.base_exec_prefix. Define cómo se escriben y consumen las nuevas claves base-prefix y base-exec-prefix, cómo se depreca home y verifica tanto los entornos recién creados como los actualizados.
