Template for sysconfigdata module generated at build time.

This file is used as a template to generate the _sysconfigdata module
that CPython uses at runtime. It is copied verbatim (after the header comments)
into the generated sysconfigdata file.

The _build_time_vars dictionary is written before this content.

Note: mypy and flake8 errors are ignored for this template file as it contains
code that is valid only in the context of the generated sysconfigdata module
(e.g., _build_time_vars is injected, RelenvException is in generated context).
