[10.x] Adds ability to restore/set Global Scopes

[DarkGhostHunter]

What?

Allows the static array for Global Scopes to be restored by allowing to retrieve and set them all.

use Illuminate\Database\Eloquent\Model;

$scopes = Model::getAllGlobalScopes();

// Handle request..

Model::setAllGlobalScopes($scopes);

Why?

Because the current implementation of Global Scopes, by being static, has some problems on Laravel Octane:

• Global Scopes list can bleed into other requests in Laravel Octane.
• Global Scopes with dynamic names can cause memory leaks.

This only adds two new methods to retrieve and set ALL of the Global Scopes. This allows Laravel Octane to save the original list, and restore it before handling the next request, avoiding bleeding or memory leaks.

It doesn't fix the problem with modifying a Scope instance state. This should be documented on Laravel Octane by warning the developer that Scope instances are shared across requests and, if needed, these should be manually "reset" before the next:

use App\Models\Album;
use App\Scopes\ShowPrivatePhotos;
use Illuminate\Support\Facades\Event;
use Laravel\Octane\Events\RequestHandled;
 
/**
 * Register any other events for your application.
 */
public function boot(): void
{
    Event::listen(RequestHandled::class, function () {
        $privateScope = Album::getGlobalScope(ShowPrivatePhotos::class);

        $privateScope->removeAuthenticatedUserID();
    });
}

BC?

Nope, only additive.
