gh-37319: `build/pkgs/meson`: Update to 1.3.1, require >= 1.2.3 for Python 3.12 support, reject meson installed in inaccessible user schemes
    
<!-- ^^^^^

<!-- Describe your changes here in detail -->

As reported in https://groups.google.com/g/sage-
devel/c/9ETciH8efTE/m/UfUO7xmsAQAJ, our `configure` script currently
accepts "system" meson that will not be functional in our venv.
```

```

Also tightening the version requirement. Only needed for Python 3.12
support (https://github.com/mesonbuild/meson-
python/blob/main/pyproject.toml#L36), but we do this unconditionally for
simplicity.

Also updating meson to latest and changing to a wheel package.
