Investigate ways of bundling PIE with a PHP install.

Discussed in #322

The https://www.php.net/downloads.php was updated but I think PIE is not yet shipped with PHP itself.

While I think it would be great if I install PHP via brew that PIE is part of it. We at current state maybe can just extend the downloads page.
