Add method to Eloquent to save and return a Model

[gisostallenberg]

It would be neat if we could save a model and have it returned after save.
I know the create method exists, but it does not work well with relations.

The following macro works well:

Illuminate\Database\Eloquent\Builder::macro('store', function(array $options = []) {
    return tap($this->getModel(), fn($model) => $model->save($options));
});

But this could also be added to the builder by default:

    /**
     * Save a model and return the instance.
     *
     * @param  array  $options
     * @return \Illuminate\Database\Eloquent\Model|$this
     */
    public function store(array $options = [])
    {
        return tap($this->model, function ($instance) use ($options) {
            $instance->save();
        });
    }

This would allow for the following:

$myModel = (new MyModel(['someAttribute' => 'that is fillable']))
    ->relatedModel()->associate($myRelatedModel)
    ->store();

I'd rather see this as an opt-in thing on ->save(); something enabled in a service provider.

Model::returnInstanceOnSave();

Only if it would be forced to throw exception on failure.
