[8.x] Added 'pipeInto' method to EnumeratesValues trait

[pascalbaljet]

There is already a mapInto method to map each value into a new class, but with this method, you can pass the collection instance into a new class. Works great when combined with API Resources.

Before:

$categories = Category::query()
    ->orderBy('name')
    ->get()
    ->pipe(function (Collection $categories) {
        return new CategoryCollection($categories);
    });

After:

$categories = Category::query()
    ->orderBy('name')
    ->get()
    ->pipeInto(CategoryCollection::class);
