[LiveComponent] Add support for live components in reusable bundles

[javiereguiluz]

Symfony UX doesn't officially support defining Live Components in reusable bundles (see #3064). However, if you add the following config for your live component, it works inside a bundle:

    // config/services.php
    return static function (ContainerConfigurator $container) {
        // ...

        $services->set(ProductSearch::class)
            // ...
            ->tag('twig.component', [
                'live' => true,
                'route' => 'ux_live_component',
                'url_reference_type' => true,
            ])
            ->tag('controller.service_arguments');
    };

We don't want to promote this because it's a hack that could break at any moment because of Symfony UX changes. But, hopefully there's a way to make this work officially in some way to allow Live Components be distributable more easily in Symfony bundles.

Thanks!
