php 8.1 support with opis/closure:4.x-dev

[xpader]

php-di now can't support closure serialize with php 8.1, need depend on opis/closure:4.x-dev.

Opis/closure 4 uses FFI: opis/closure#59

I'm afraid this will not really work with PHP-DI as FFI is an extension that will not be installed everywhere. Laravel will probably get the same problem here.

Laravel has forked opis/closure: https://github.com/laravel/serializable-closure

Here's already a PR: #793

Any update on this?

@mnapoli PR #808 created that applies the minimum changes required to resolve this.
