Drop Engine repacking - Directly use Winehq portable releases

[Gcenx]

The idea we floated, that would speed everything up.

The idea, download winehq portable release directly.
When making a wrapper, unpackaged the portable release making the usual wswine.bundle.

Unless we also drop wswine.bundle and instead extract the contents into /Resources/wine (but this would require more backend changes) meaning later signing/notarizing might be simpler.
