[8.x] Add pipeThrough collection method

[stevebauman]

Description

This PR adds the pipeThrough() method for collections, allowing developers to insert an array of pipe callbacks that can manipulate the collection, carrying the return value from the previous pipe into following pipes.

Usage

$pipes = [
    fn ($podcasts) => $podcasts->each(
        fn ($podcast) => $podcast->process()
    ),

    fn ($podcasts) => $podcasts->sum(
        fn ($podcast) => $podcast->hasProcessed()
    ),
];

$processed = Podcast::all()->pipeThrough($pipes);

Let me know if you would like anything adjusted. Thanks for your time! No hard feelings on closure ❤️
