Generates the autoload file at the specified location.

This only writes a bit of PHP that includes the autoload file that Composer generated. Drupal does this so that it can guarantee that there will always be an `autoload.php` file in a well-known location.

Parameters

\Composer\IO\IOInterface $io: IOInterface to write to.

string $package_name: The name of the package defining the autoload file (the root package).

string $web_root: The path to the web root.

string $vendor: The path to the vendor directory.

Return value

\Drupal\Composer\Plugin\Scaffold\Operations\ScaffoldResult The result of the autoload file generation.
